527 | * | ||
528 | * It is possible to also sets the icon of the application easily: | ||
529 | * | ||
530 | * @li Create an icon with your favorite image creator. The Gimp is a | ||
531 | * good choice. Create several images of size 16, 32 and 48. You can | ||
532 | * also create images of size 24, 64, 128 and 256. Paste all of them | ||
533 | * in the image of size 16 as a layer. Save the image of size 16 with | ||
534 | * the name my_icon.ico. Put it where the source code of the | ||
535 | * application is located. | ||
536 | * @li Create my_icon_rc.rc file with your code editor and add in it: | ||
537 | * @code | ||
538 | * 101 ICON DISCARDABLE "my_icon.ico" | ||
539 | * @endcode | ||
540 | * @li With Visual Studio, put that file in the 'Resource file' part | ||
541 | * of the project. | ||
542 | * @li With MinGW, you have to compile it with windres: | ||
543 | * @code | ||
544 | * windres my_icon_rc.rc my_icon_rc.o | ||
545 | * @endcode | ||
546 | * and add my_icon_rc.o to the object files of the application. | ||
547 | * | ||
548 | * @note The value 101 must not be changed, it's the ID used | ||
549 | * internally by Ecore_Win32 to get the icons. | ||
