Declaration

type timage = class(tscrollingwidget)

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.

Properties

Published property bitmap: tmaskedbitmap read fbitmap write setbitmap;

To load an image at runtime with bitmap.loadfromfile, add the unit implementing the wanted format to uses first — e.g. mseformatbmpico, mseformatjpg, mseformatpng, mseformatpnm, mseformattga or mseformatxpm (unit msegraphicstream lists the currently registered formats). To embed a fixed image at design time instead, assign it through the ellipse button next to bitmap in the object inspector, which stores it directly in the .mfm file.
