An Application Icon - .pxm format

[slava]

As I unerstood from the manual, in order to add an icon to the application I need to do:

setWindowIcon(QIcon("icon.pxm"));

What is this pxm format? I have .jpg icons or .ico icons but not pxm. What do I use to create .pxm? Can I use the .ico instead?

Dear Slava!

setWindowIcon(QIcon("icon.pxm"));
What is this pxm format? I have .jpg icons or .ico icons but not pxm. What do I use to create .pxm?
First I want to correct you, There is no format of PXM in Qt. XPM is a X11 Pixmap format.

setWindowIcon(QIcon("icon.xpm"));
And you can create this using KolourPaint and save as a file X Pixmap Image (filter option of save as dialog).

Can I use the .ico instead?
Yes! you can use any of the following format;

thank you. Could you please explain me how to do that exactly?

If I do:

setWindowIcon(QIcon("app.jpg"));

... nothing happans, do I need to convert the image first somehow?
