About the Layout Editor

The Layout Editor is a graphical design facility for creating and arranging interface items and graphic objects in a form. In the Layout Editor, you work on a single canvas. Canvases are displayed in windows at runtime. You specify the window a canvas will be displayed in by setting the canvas's Window property.

Layout Editor Context
 
The title bar of the Layout Editor window displays context information, including the name of the current form, the name of the canvas being edited, and the name of the current block. When you create an item by drawing it on a canvas in the Layout Editor, Oracle Forms assigns the item to the current block, as indicated by Layout Editor block context. You can change Layout Editor block context using the Block poplist on the toolbar.
 
Rulers
 
The horizontal and vertical rulers at the top and left side of the workspace provide a reference for sizing and arranging objects in the Layout Editor. To hide rulers, deselect the Rulers option on the View menu.

Layout Editor ruler units can be set to character cells, inches, centimeters, or points. To display the Ruler Settings dialog, choose View | Customize Rulers/Grid.
 
Grid
 
There is a grid defined within the workspace that helps you position objects. The grid is rendered in the current ruler units. To hide the grid lines, deselect the Grid option in the View menu.
 
Ruler Guides
 
Ruler guides are horizontal and vertical dotted lines that can be used as references when aligning objects on a canvas. To create a ruler guide, position the pointer on either ruler, then click and drag into the workspace. Ruler guides are not displayed at runtime.

To move a ruler guide, drag it to a different location. To delete a ruler guide, drag it out of the workspace. To temporarily hide ruler guides without deleting them, deselect the Ruler Guides option in the View menu.
