How the CurFrame System Variable Works
To access the FrameExec object for the current frame from OpenROAD, use the CurFrame (for current frame) system variable. CurFrame can be used to change attributes such as:
• The size of the frame
• The background color of the frame
• The field that receives the input focus after the current event block has completed
For more examples of using CurFrame and information about how to reference the FrameExec object of another frame, see
Inter-Frame Communication Techniques (see
