Working with Stacked and Tab Canvases in the Layout Editor
You can create and edit both stacked and tab canvases directly in the Layout Editor.
Creating
- To create stacked or tab canvases, you can use the Stacked Canvas or Tab
Canvas buttons on the Layout Editor toolbar.
- To create a tab canvas
- First display the Layout Editor.
- Click
in the toolbar, then click-drag a rectangular region where you want the
tab canvas to appear on the underlying content canvas.
Once you have created the tab canvas in this manner, you can immediately resize
or move it while still in the Layout Editor.
Editing
You can use the Layout Editor to edit items on a stacked or tab canvas in two
ways: (1) directly, or (2) on the stacked view of a content canvas.
To directly edit a stacked or tab canvas:
- Invoke the Layout Editor, select the appropriate canvas from the Canvas
combination box at the top of the window.
- Move, resize or manipulate the items of the canvas.
To edit a stacked or tab canvas on the stacked view of a
content canvas:
- Invoke the Layout Editor, display the appropriate content canvas by choosing
View | Stacked Views.
- Select the appropriate canvas from the Stacked Canvases dialog.
- Move, resize, or manipulate the items of the canvas.
Automatic Synchronization
Oracle Forms automatically synchronizes items on the stacked view of the
content canvas and the corresponding item on the actual stacked canvas. For
example, any movement, resizing or changes in visual attributes to an item on
a stacked canvas from the stacked view on the content canvas is reflected in
the stacked canvas when invoked from a Layout Editor. Similarly, when changes
are made to items on a stacked canvas from a Layout Editor, the changes are
reflected in the stacked view on the content canvas.
