Declaration

type tcuchart = class(tscrollbox, ichartdialcontroller, istatfile, iframe)

Description

This item has no description. Showing description inherited from tmsecomponent.

Extends the FPC tcomponent with object linking facilities and the like; base of every MSEgui component. This unit, mseclasses, must be added to uses after classes in code that also uses a third-party unit expecting the plain FPC tcomponent (e.g. TPSScript.Create(TComponent)), since MSEgui forks the FPC classes unit.

Public procedure paint(const acanvas: tcanvas); override;

This item has no description. Showing description inherited from twidget.paint.

invalidate (called automatically, e.g. by setcaption) adds the widget's client area to its window's update region; once the main event queue is empty, the update regions of all windows are painted, widget by widget, bottom-up in z-order, by paint. If the widget's color is not cl_transparent, the area is first filled with that color; then, if active, frame is painted (filling its own client area with colorclient if that is not cl_transparent), then, if active, face; the widget's own content (e.g. a caption) is painted last, on top of that background. When code changes a widget's widgetrect directly rather than through a property that does it automatically, it must invalidate the old widgetrect before the change and the new one after, so both the vacated and the newly covered area get repainted.
