TGView Class Reference

A TGView provides the infrastructure for text viewer and editor widgets.

It provides a canvas (TGViewFrame) and (optionally) a vertical and horizontal scrollbar and methods for marking and scrolling.

The TGView (and derivatives) will generate the following event messages:

  • kC_TEXTVIEW, kTXT_ISMARKED, widget id, [true|false]
  • kC_TEXTVIEW, kTXT_DATACHANGE, widget id, 0
  • kC_TEXTVIEW, kTXT_CLICK2, widget id, position (y << 16) | x)
  • kC_TEXTVIEW, kTXT_CLICK3, widget id, position (y << 16) | x)
  • kC_TEXTVIEW, kTXT_F3, widget id, true
  • kC_TEXTVIEW, kTXT_OPEN, widget id, 0
  • kC_TEXTVIEW, kTXT_CLOSE, widget id, 0
  • kC_TEXTVIEW, kTXT_SAVE, widget id, 0
