Modifying Pushbuttons

[Sharon Daniel]

Hi,


I am trying to modify the way the pushbuttons i use will show. I want my pushbutton to behave just like the desktop. I will be able to move them around and double click the for opening. My questions are :

1)how to change the color of the text and the icon to be in blue background ?

2)how to change the text of the pushbutton.


i have made it in createing the pushbutton with the icon using OWNERDRAW, i have made it to move the pushbutton around, and i do know the area of the icon and the text.


I do not want to use listview, because i am changing a behavior of a running program and i have hooked the pushbuttons of that program and now i am chnaging the way it shows on the screen.


Thanks in advance for any idea.

Button is just another window - when you need to display your own graphics in it, you will need to hook the WM_DRAWITEM message. In the handler you put code like if you are drawing into a normal window. You need to get a DC, then draw on it (first fill the background, then draw the icon, then the text). Then release the DC.

Hi,

I have written a button class that takes care of changing button text, back color and fore color. I'm giving ColorButton.h and ColorButton.cpp files. All you need to do is add a member variable to your button of this class (CColorButton) and use the functionality.
