Declaration

type tgraphdataedit = class(tactionpublishedwidget, igridwidget, istatfile, iassistiveclientgridwidget, iifidatalink)

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.

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.

For a tcustombooleaneditradio group, ondataentered only fires on the item the user actually clicked, not on the other items of the group that change state as a consequence (their value changes to False). Use onchange, or a single ondataentered handler shared by all items of the group, to react to any change within the group.
