How to print a TTreeView (Views: 706)
Problem/Question/Abstract: How to print a TTreeView Answer: var bmp: TBitmap; begin bmp := TBitmap.Create; try bmp.width := treeview.width; bmp.height := treeview.height; bmp.canvas.lock; try treeview.perform(WM_PRINT, bmp.canvas.handle, PRF_CHILDREN or PRF_CLIENT or PRF_NONCLIENT); finally bmp.canvas.unlock; end; { ... print the bitmap as device-independent bitmap } finally bmp.free end; end; Drawing directly to the printer canvas is probably possible but you have to mess with mapping modes, scale the printer canvas, move its origin and so on, the above may be easier to code, especially if you already have a PrintBitmap routine flying around somewhere. |
