2.2.19 Write string mode

The purpose of write string mode is to add and edit strings. The string

• has a maximum of 255 characters
• may not contain carriage return, line feed or tab characters
• is always on one line
• has one set of style attributes for the entire string.

String editing in the form of a string edit box is built into 4D CAD.

Dependent on the setting of theWriteStringModeModifiers parameter of CADSetAreaPrefs, you can also

• Hold down the command key to use Zoom in mode
• Hold down the option key to use Zoom out mode
• Hold down the shift key to use Drag-scroll mode
• Press the space bar to switch to Drag-scroll mode.

Important
The application can overrule the built-in string editor with CADSetAreaPrefs (also see kCADEventIDWriteString and Events and the EDtCEvent method in DemoCAD).
