[GD-Windows] edit control (or CEdit) when is the text drawn ?

[Lionel F. <li...@mi...>]

Hello,

I want to make a (very basic) CEdit with custom colors and syntax parsing.

I can change the whole text & bkgnd colors using OnGetDlgCode,
WM_CTLCOLORDLG, WM_CTLCOLORSTATIC and WM_CTLCOLOREDIT but it's not enough,
because the whole text is drawn with the same colors.

So, I rewrote OnPaint to draw the text myself with DrawText. Fine.

BUT, when I just select some text in the edit control, the text is drawn
without any WM_PAINT message, (using the colors provided by
WM_CTLCOLORSTATIC).
What message is send to the edit window when some text is selected ? I have
try to catch the message with Spy++, but I don't understand why WM_PAINT is
not called.

Thank you for any help !
Lionel.

You want to catch the EM_SETSEL message. (start in wParam, end in =
lParam).=20

if start is -1 the selection is being removed. If end is -1 and start is =
0
then the whole edit control is being selected.
