Component
Component Array
In the Form Design editor, components can be added to the form by selecting them on the Component bar.
By using Component Toolbox, which is a collection of defined components in the TypeDefinition, you can create components by dragging and dropping them. Open the Component Toolbox by selecting View > Toolbox from the menu.
Frequently used components are listed in the following table.

When you drag the mouse on the empty space of the Form Design window, a rectangular region will be selected. The starting and ending points, width and height of the rectangle, in pixels, will be displayed.
If a component has been selected from the Component Toolbox or toolbar, the component will be created in the identified area. If you do not drag the mouse and just click on the screen, the component will created at the default size specified in the TypeDefinition.
The Form Design toolbox includes components that are not displayed to the user. These components may be displayed on the screen during application development so that component properties can be managed.
If the Invisible Layout window is not displayed, you can show it by selecting Show Invisible Object Area from the Design Window [Popup Menu].
In the Invisible Layout, functions such as icon display are provided in the popup menu as illustrated below:
Menu | Function |
---|---|
Edit | Opens the appropriate editor for the selected object |
Cut | Cuts the selected object |
Copy | Copies the selected object |
Paste | Pastes an object |
Delete | Deletes the selected object |
View | Changes the way invisible objects are displayed: Big, List, Small, and Report |
Selection Change
When designing a form, you can select one or more component by using various key combinations.
By pressing Tab, you can move the selection from one component to the next, based upon the defined tab order, Shift+Tab will move the selection in the reverse order.
(See Tab Order)
The multi-selection function can add or delete a selection by using the Ctrl key or Shift key.
If you activate the selection function and click-and-drag over an area with the mouse, all components in the area will be selected. If you do the same while pressing the Shift key, items already selected will be undone and all other items will be selected.
By pressing ESC and selecting a component, you can select the superior component of the selected component.
Size Change
When component tracker points are activated, dragging and dropping one point changes the size of the component.
If several components are selected, all of the component sizes will change in the same proportion.
Pressing Shift while changing a component's size will modify the width and height in fixed proportion to each other.
Pressing Ctrl while changing a component's size, will change the size equally on both sides of the middle of the component.
Pressing Shift+Ctrl while changing a component's size will increase both the width and the height in proportion to one another and equally on both sides of the center of the component.
You can also change the component size by pressing the direction keys while pressing <Shift> key.
Location Change
A selected component (or components) can be moved by using the arrow keys on keyboard. If you move the components with the mouse while pressing CTRL, the component(s) will be copied to the destination.
Use the Magnetic function to make minute adjustments automatically if you put other components or options close to the DotGrid. The Magnetic function can be activated based on the option value on the [Tools - Options - Form Design] menu for DotGrid or other components.
The Magnetic function can be overridden by pressing ALT while moving components.
Tab Order
The tab order refers to the sequence in which you make moves among components by pressing the tab key in the middle of running an application.
Tab Order Edit
You can control the run-time tab order for components by pressing Ctrl+D when the Design Window is activated, or through the Tab Order Edit Menu in the Design Window [Popup Menu].
When you move a mouse cursor over a certain component, its color will change to red while the component of the next tab order will be highlighted in orange. If multiple components overlap, those components will be spread out for easy editing.
The Tab Order Edit mode supports the below context menu.
Menu | Shortcut | Description |
---|---|---|
Accessibility Simulation Mode | Toggles on/off the simulation in which you can see how focus actually moves by pressing the Tab key in an accessibility-enabled application. - Toggled off: If a component's tabstop property is set to false, focus will not move to the component. - Toggled on: If a component's accessibility.enable property is set to false, focus will not move to the component. | |
Set Next Tab Order | Specifies the value of Next Tab Order | |
Next Tab Order | Up | Increases the Next Tab Order value by 1 |
Previous Tab Order | Down | Decreases the Next Tab Order value by 1. The minimum value is 0 |
Next Tab Order(10) | Right | Increases the Next Tab Order value by 10 |
Previous Tab Order(10) | Left | Decreases the Next Tab Order value by 10. If the current Next Tab Order value is 10 or smaller, the value will become 0. |
Tab Order Increase | PageUp | Increases all the tab order values by 10 times. This feature is useful when you intend to insert components between tab orders. For instance, assume that there are two components whose tab order values are 3 and 4, respectively. You can insert other components between them by multiplying their values to 30 and 40—in this case, you can insert up to 9 components ranging from 31 to 39. |
Tab Order Decrease | PageDown | Minimizes the gap between current tab orders. Adjusts the value of the first tab order to 0 and arranges the others in consecutive sequence. |
Tab Order List | Opens the Tab Order List window, which shows tab order in a list form and allows you to edit the list | |
End Edit | Enter | Ends the Tab Order Edit mode after saving changes |
Cancel Edit | Esc | Ends the Tab Order Edit mode without saving changes |
Tab Order List
The Tab Order List window presents tab order in the form of an editable. You can change tab order by selecting one or more items and then pressing one of the below four buttons.
You can open the Tab Order List window by accessing [Design > Tab Order List] in the menu or [Tab Order List] in the context menu opened from the Design panel.
You cannot edit the other information items (i.e. id, text, tabstop and accessibility) in the list than tab order.
Tab Order View
The Tab Order view is used for checking the tab order defined on the current screen. Turn on/off (toggle) the function by using the Tab Order View in the Design window [popup menu]. When the function is activated, you can see two numbers on the top left of the component, as shown in the picture below.
The numbers in the blue boxes indicate the order of tabs. Change the order by revising the tab order property of components or by using the Tab Order Edit function.
The numbers in the green boxes indicate the Z-Order of components. Z-Order defines the display order of components when the components are overlapped. A component that has a bigger number is moves to the front.
Change the Z-Order by using one of the four functions on Align toolbar, or by changing the order of arranged XML code on Source tab:
Bring to Front
Send to Back
Bring Forward
Send Backward
Guide Line
The Guide Line function is included with the Ruler and allows the developer to make vertical/horizontal lines wherever desired to help in aligning components.
Create a guide line by clicking a spot on the ruler. Move a guide line by selecting and dragging it with the mouse. Delete a guide line by selecting it and dragging and dropping it out of the Design Window or double-clicking on the inverted triangle on the guide line.
Setting Properties
The properties for a selected component are displayed in the Properties Window. When you modify the property values, they are immediately applied to the component.
When a property has subordinate properties as shown in the figure below, an icon that can expand the properties will be shown in front of the property. Properties are automatically synchronized with their subordinate properties and vice versa.
Components that are visibly expressed on the Form Canvas can show Style Attributes. Each attribute can be edited, changing the style of component.
Set Font
For components with text properties including fonts, you can modify the font properties.
Designate color properties directly instead of using the font dialog box.
Nexacro Platform applications do not have their own fonts. They use the fonts installed with the operating system. You can prioritize available fonts so that you can find them more easily when developing applications. How are available fonts prioritized?
Data and Event Processing
Bind
In Form Design, you can bind selected components to datasets by dragging and dropping a dataset onto the component, or by selecting Bind mode from the Properties Window.
When using drag and drop, depending on the type of component, the Inner Bind Dataset function or Bind Item Editor function will be accessed.
Inner Bind Dataset
When a dataset is bound to components that can display data in a list form, such as List Box or Combo, the Inner Bind Dataset is accessed because it can designate the dataset column to use in a list.
Properties | Description |
---|---|
Codecolumn | Designates column that is used internally |
Datacolumn | Designates column that is displayed to the user in the component |
Bind Item Editor
When the dataset is bound to components that can display one item like Edit or Button, the Blind Item Editor function is accessed.
Properties | Description | |
---|---|---|
1 | Bind ID | User classification ID |
2 | Component | ID of component that dataset is bound to |
3 | Property | Component property that dataset is bound to |
4 | Dataset | Dataset that is bound to the component |
5 | Column ID | The dataset Column ID that is bound to the component |
6 | Adds Bind Item | Adds a new bind item |
7 | Delete Bind Item | Deletes the selected bind item |
When a dataset is bound toi typo a form or component, it is displayed in the Project Explorer window on the item for easy verification, as shown below:
Grid Contents Editor
The Grid Contents Editor is used to edit the grid’s contents properties. There are many cell unit properties besides the properties that can be seen in the Properties window.
Access the Grid Contents Editor by double-clicking the Grid component on the Design Window.
Where exactly is this? This entire section needs clarification. Need to add content about how to get the GCE open.
The Grid Contents Editor is composed of the main edit window and the Design Source window.
In the main edit window, you can add or delete a cell by using the popup menu and shortcut keys, or the edit properties. The main edit window displays the column index at the top, followed by the head, body, and summary.
Add a column or row from the Popup Menu of main edit window.

Select the Design Source tab to display the Grid Contents in XML. You can edit the XML directly.
Adding Events
You can add an event to a component by selecting the component, and then Event Edit Mode from the Properties Window. You can enter the event directly, or create it automatically by double-clicking the relevant event listed in the Properties.
Double-clicking the component in the toolbar above the Form Design window will create the main event for that component automatically.
Screen layout
Form layout
When creating a new form, you can designate the layout, or set additional layouts, after creating the form in the “New Form Wizard.” Form layout is used to provide optimized screen composition based on the user’s screen size.
Screen Composition
The following figure shows three layouts for the form using a tabbed display (with the tabs on the left). The location of the tabs can be changed by using [Tools > Options > Form Design > Layout Manager > Layout Tab Style].
Selecting a newly added layout tab will display that tab's layout. From the context menu you can add or delete layouts, as well as view a list of available layouts. The selected layout is displayed as the area of the form enclosed by a red dotted line.
Menu Function | Description |
---|---|
Add Layout | Creates a new layout at the end of the “layout tab”. The layout name must be unique. |
Copy & Add Layout | Adds a layout at the end of the “layout tab” by copying the currently selected layout. |
Delete Layout | Deletes the selected layout |
Layout List | Shows a dialog box with information about the layouts currently in use. |
When you select the form from the Project Explorer, the context menu lists options for viewing layout information.
The following figure illustrates the Layout List for the sample DragForm.
Layout Property | Description | |
---|---|---|
1 | Template | Functionality that brings and adds layout information created with a template |
2 | Add Layout | Button that adds layout information to be used in the form |
3 | Delete | Button that deletes the layout selected on the list |
4 | Grid that shows layout information for the form | • Name: layout name (Default name is case sensitive. Name must be unique in form.) • Screen: screen name used by layout • Width: layout width in pixels • Height: layout height in pixels |
Restricted Design Functionality
The "Default" tab provides all layout functionality, most notably the ability to add new controls. Additional layouts mostly support only rearranging the controls added to the default layout. Details are shown in the table below:
Design Functionality | Default | Additional Layout |
---|---|---|
Component creation, deletion | √ | |
Component copying, cut, and paste | √ | |
Component move | √ | √ |
Tab order change | √ | √ |
Form domain indication | √ | |
Invisible Object addition,deletion, selection | √ |
Properties Window
Height and width form properties can be revised by each layout. When changing the size by dragging the mouse tracker, the property values of height and width for the layout will be changed accordingly. The property values related to form size shown on the Properties window are identical to those shown on the Layout List.
Property values changed from the default values in a new layout tab are displayed in bold blue color.
Bold and color formatting are used on the Properties window to indicate additional information about property values:
Color | Bold? | Information |
---|---|---|
Black | Default values with themes and styles are applied | |
Black | √ | Values revised on the Default tab are different from those default values applied with themes and styles |
Blue | √ | Values revised on the newly added layout tab are different from those of the Default tab |
Component IDs can be revised only on the default layout tab.
Sub-layout
Components such as Div, PopupDiv, and TabPage that contain content within themselves can have several layouts just like forms. To distinguish a component layout from a form layout, a component format is called a "Sub Layout". A sub layout differs from a form layout.
You cannot edit button components included in a Div component directly on a new form layout. For this reason you need the screen composition optimized for the given component’s size. With a sub-layout, the target component’s size will change as the form layout changes. That way, you can have a fully optimized screen by simply changing sub layouts.
Layout Option
To edit content included in components such as Div on an additional layout:
Select Show Sub Layout Name to check the name of the sub-layout applied to the current component
Select Sub Layout Edit to edit the sub-layout
Select Set Sub Layout to adjust the sub-layout to the size of component
Sub Layout Editor
If you select the Sub Layout Edit option from the context menu or double-click components, you can see the Sub Layout Editor displayed as below. The default sub layout’s size is identical to that of the selected component.
If the URL’s properties are linked with other forms, a sub layout edit is not supported. Instead, you can edit by opening the linked form with the context menu or by double-clicking the component.
The Sub Layout Editor has the following properties:
In sub layout editor mode, the area of the parent component (Div component) is indicated by a red dotted line.
Allows editing of subordinate components hidden from view on form design status
Only components and lower-level components can be selected or edited
Although you can revise the size of a sub layout, you cannot change its location
The appearance of the context menu may differ slightly depending on whether or not you select a subordinate component as well as by the type of component.
Menu Function | Description |
---|---|
Add Sub Layout | Opens a dialog box to create a new sub layout. The default size of an added sub layout is equal to the current size of a relevant component. You cannot enter the name of a sub layout currently in use. |
Delete Sub Layout | Deletes the currently selected sub layout from the list. The Default sub layout cannot be deleted. |
Sub Layout List | Displays a dialog box to revise all sub layouts in use on the component. The name of the default sub layout cannot be changed freely. What does this last sentence mean? |
Show Sub Layout Name | Checks the name of the sub layout applied to the current component. |
Fit to Componet | Adjusts the size of the currently-edited sub layout for the relevant component. |
Apply Size & End Edit | Applies the size of the sub layout currently being edited to the target component and exits the Sub Layout Editor |
End Edit | Applies the revision to the sub layout and exits the Sub Layout Editor |
Cancel Edit | Cancels all edits and exits the Sub Layout Editor |
The Sub Layout Editor manages form design and separate Undo data. Once the Sub Layout Editor is terminated, the Undo data will be deleted as well.
The content in the Sub Layout Editor can be undone within the Editor itself. However, once the Editor is terminated, the data will be treated as a single task and added to the undone data. If you execute Undo on form design, all items revised on the Sub Layout Editor will be reverted to their status before the Sub Layout Editor was invoked.
In a case where a Div component is included within another Div, the included Div can be edited just like any other subordinate components. Moreover, an additional sub layout for the lower-level component is available. Just select the Div component you want to edit and double-click to launch a sub layout editor.
The lower-level Div component cannot be selected when its layout is not a default. However, double-clicking will launch a sub layout editor.
If you double-click another Div component while using a sub layout editor, you can change the sub layout to edit.
If the area of a subordinate component is larger than that of the parent Div component, the followings are how to select the Div component by mouse. Use the following methods in order.
1) Select the subordinate component first.
2) Press Esc key to select the parent component (Div component).
3) Press Menu key to call a context menu and select Sub Layout Edit.
Properties Window
You can revise a component's style and some of the properties within a sub layout. For a Div component, the revision is saved in the <Div> tag on the default sub layout while the revision made in additional sub layouts is saved in <Layout>.
This is the first time, I think, that XML is shown in this document. We should add general content in an appropriate location about the XML representations of various components.
... <Layouts> <Layout> <Div id="Div00" left="10" top="10" width="250" height="250" style="background:red;"> <Layouts> <Layout width="250" height="250"/> <Layout name="iOS" width="150" height="150" style="background:blue;"/> </Layouts> </Div> </Layout> </Layouts> ...
Step
Step is a function which can develop pages that consist of several steps in one form. When you control the stepcount
property value, the step will appear as shown in the figure below.
stepcount
Indicates the step area currently being edited. The edited area may change depending on the location of the mouse pointer.
Each step area is indicated by the blue dotted line.
Even if there are several steps, the form’s size does not change. At runtime, only one step is visible with the step changing according to the user interaction.
positionstep
The positionstep
property corresponds to the component's position to the step areas.
positionstep value | Description |
---|---|
0 | Component is out of all of the step areas |
-1 | The component is shown in all of the steps:
|
... <Layouts> <Layout width="300" height="450" stepcount="3"> <Button id="Button00" text="Button00" left="60" top="60" width="120" height="50"/> <Button id="Button01" text="Button01" left="60" top="60" width="120" height="50" positionstep="1"/> <Button id="Button02" text="Button02" left="60" top="60" width="120" height="50" positionstep="2"/> <Button id="Button03" text="Button03" left="60" top="160" width="120" height="50" positionstep="-1"/> </Layout> </Layouts> ...
If a component is moved to a different step from the design form screen, the value of positionstep will change with an adjustment of the position value to the given step.
If the position property value is out of the step’s boundaries; however, the value of positionstep will not change.
Position
The location of forms and components on Nexacro Studio can be designated by setting the property values of left, top, right, bottom, width, and height. Each property value can be indicated by pixel unit (px) or percentage (%).
Tracker
When you select a component, the relevant tracker according to the position property is indicated in red.
Ruler / DotGrid
To assign layouts easily when designating locations on the form design, the ruler unit can be either pixel unit (px) or percentage (%).
On the ruler context menu, you can change the way the ruler and DotGrid units are measured by selecting Show Pixel Ruler / Show Percent Ruler.
The following figure illustrates size information when revising the size of only one selected component. The size unit in this case depends on the unit of the ruler.
Position Editor
For the user to set up position information easily, a separate editor is provided. The Position Editor can be executed in the mini toolbar that appears when selecting a component.
The mini toolbar provides functionality that changes the frequently used style property menu directly.
The revised values on Position Editor will be reflected in the property values of left, top, right, bottom, width, and height.
Properties Window
You can change the unit of property values for left, top, right, bottom, width, and height on the Properties window.
The Form, Mainframe, and Childframe elements cannot be designated in percentage units. Width and height properties for these must be designated in pixel units only.
