Set the size of the GUI by resizing the grid area in the Layout Editor. Click the lower-right corner of the layout area and drag it until the GUI is the desired size. If necessary, make the window larger.
As you drag the corner handle, the readout in the lower right corner shows the current position of the GUI in pixels (regardless of the GUI Units property setting). Existing objects within the GUI resize with the GUI window if their Units are normalized.
Note Setting the Units property to characters (nonresizable GUIs) or normalized (resizable GUIs) gives the GUI a more consistent appearance across platforms. See Cross-Platform Compatible Units for more information.
Existing objects within the GUI resize with the GUI window if their Units are normalized. To prevent them from resizing with the GUI window:
Set each object's Units property to an absolute value, such as inches or pixels before enlarging the GUI.
To change the Units property for all the objects in your GUI simultaneously, drag a selection box around all the objects, and then click the Property Inspector button and set the Units.
When you finish enlarging the GUI, set each object's Units property back to normalized.
Click the down arrow at the far right in the Units row, and select inches.
You can make maximum use of space within the Layout Editor by hiding the GUIDE toolbar and status bar, and showing only tool icons, as follows:
From the View menu, deselect Show Toolbar.
From the View menu, deselect Show Status Bar.
Select File > Preferences, and then clear Show names in component palette
