I am trying to draw some geometric objects on canvas which may overlap each others in an ordered they have been drawn in VC++.net (or VC#). It is simply done by drawing Rectangle or other related drawing methods in order. But the problem comes up when I try to move or delete one specific object between the overlapped ordered objects without affecting the appearance of other ordered overlap object! this is seems to be related to the concept of Object Oriented Programming for graphic programming which I expect to be doable in GDI+ but I couldn't find any related methods to do things like that. can anyone help how can I do this in GDI+ ?
Dear Behrad. In GDI+, you have no choice to edit, move or delete existing shapes drawn to a surface, because they are pixel-based. You should handle this manually through coding techniques. If it is troublesome, I recommend you to use WPF instead of Windows Forms Applications, where it provides you with components for common shapes so they are editable and moveable.
thank you amirhosain, but how does microsoft windows forms and object interact together without any redrawing when GDI+ is the graphic core library of the windows?
i suppose it should exist an extended library to GDI+ to support animating and overlaping object drawing in a structured approach ! WFP is kinda new technology and I guess it should exist something more older than WPF !
