A screen can contain another screen within it. If the child screen requires access to the
parent screen, you can use a property in the child screen to access any component or property in the
parent screen.
About this task
To enable a child screen to access a parent screen, use the following the procedure:
Procedure
- Click on the Palette tab in the Designer Workbench.
- Right-click on the Custom Components option in the Others
category.
- Check the box by Parent Handle, which is an out-of-the-box
preset provided with the Designer Workbench.
- Move your cursor over the canvas until you see the tool
tip Click to add customct in screen.
- Right-click or left-click where you want to add this access
handle.
- Make any property adjustments to the handle. You cannot
change the default property values of either scOwnerScr (this)
or xtype (panel) in the Configure Presets View.
These default properties indicate a handle from a child screen to
a parent screen.
You can create other presets for this
control.
Once you select this preset for a Custom Component
and add the widget to the screen, you can view these two properties
in the Properties View below the Tree View. You can modify the property
values or add new properties, since you are now working on an instance
of a Custom Component that was added to the screen (and not on the
preset) and that was initialized with your values.
