How to draw a bitmap on top of button?
-
I want to draw a small arrow bitmap on top of already drawn button. I tried with calling default drawing proc before my code for drawing bitmap but it gives me some error.
OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT lpDrawItemStruct) { CDialog::OnDrawItem(nIDCtl, lpDrawItemStruct); HDC thdc = CreateCompatibleDC(lpDrawItemStruct->hDC); HGDIOBJ tobj = SelectObject(thdc, LoadBitmap(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_ARROW_DOWN))); TransparentBlt(lpDrawItemStruct->hDC, lpDrawItemStruct->rcItem.right - 20, lpDrawItemStruct->rcItem.top + (lpDrawItemStruct->rcItem.bottom - lpDrawItemStruct->rcItem.top - 16) / 2, 16, 16, thdc, 0, 0, 16, 16, RGB(255, 0, 255)); SelectObject(thdc, tobj); DeleteDC(thdc); }if i exclude "CDialog::OnDrawItem(nIDCtl, lpDrawItemStruct);" then code works, but there is no borders and caption text, just my bitmap.CImageButton class is very lousy way of replacing API function DrawFrameControl and i definitely don't need that... All that code is easily replaced with these 4 lines of code: CPaintDC dc(this); CRect rc; GetClientRect(&rc); dc.DrawFrameControl(&rc, DFC_BUTTON, DFCS_BUTTONPUSH); http://img214.imageshack.us/img214/6206/drawingfx6.png

Can you explain how do you think that i should use CBitmapButton class? As i see that class only helps in inserting bitmaps on to buttons, but it still needs me to draw the button (because my bitmap is displayed only on one small portion of button).

that's a problem :) .. I will tell you another way. Make the button owner draw, in the DrawItem Function,do as follows DrawItem() { DrawFrameControl();// This function will draw a statndard button. // here , draw your bitmap }
