|
|
*
|
|
* It is possible to also sets the icon of the application easily:
|
|
*
|
|
* @li Create an icon with your favorite image creator. The Gimp is a
|
|
* good choice. Create several images of size 16, 32 and 48. You can
|
|
* also create images of size 24, 64, 128 and 256. Paste all of them
|
|
* in the image of size 16 as a layer. Save the image of size 16 with
|
|
* the name my_icon.ico. Put it where the source code of the
|
|
* application is located.
|
|
* @li Create my_icon_rc.rc file with your code editor and add in it:
|
|
* @code
|
|
* 101 ICON DISCARDABLE "my_icon.ico"
|
|
* @endcode
|
|
* @li With Visual Studio, put that file in the 'Resource file' part
|
|
* of the project.
|
|
* @li With MinGW, you have to compile it with windres:
|
|
* @code
|
|
* windres my_icon_rc.rc my_icon_rc.o
|
|
* @endcode
|
|
* and add my_icon_rc.o to the object files of the application.
|
|
*
|
|
* @note The value 101 must not be changed, it's the ID used
|
|
* internally by Ecore_Win32 to get the icons.
