Qt4 how to set the application icon-Windows Platform

By searching for Qt assistant, we found the following descriptions:

Setting the application icon on Windows

First, create an ICO format bitmap file that contains the icon image. this can be done with e.g. microsoft Visual C ++: Select File | new, then select the file tab in the dialog that appears, and choose icon. (note that you do not need to load your application into visual C ++; here we are only using the icon editor .)

Store the ICO file in your application's source code directory, for example, with the name myappico. ICO. then, create a text file called, say, MyApp. RC in which you put a single line of text:

Idi_icon1 icon discardable "myappico. ICO" Finally, assuming you are using qmake to generate your makefiles, add this line to your MyApp. Pro file:

Rc_file = MyApp. rcregenerate your makefile and your application. the. exe file will now be represented with your icon in explorer.

If you do not use qmake, the necessary steps are: first, run the RC program on the. RC file, then link your application with the resulting. Res file.

The practice is clear:

Step 1: Prepare an ico icon.

For example, MyApp. ICO creates a file using any text editor.

Write a line in it:
Idi_icon1 icon discardable "MyApp. ICO"
 

Step 2: Save and change the name to MyApp. RC and place it and your icon MyApp. ICO in the directory of your QT project.

Step 3: Open your QT project file (such as MyApp. Pro) in a text editor and add a new line at the end of the file:
Rc_file = MyApp. RC

Step 4: Add the following code to the program:

// The app is the only qapplication object in the program.

App. setdomainwicon (qicon ("MyApp. ICO "));

NOTE: If your MyApp. RC and MyApp. ICO are not in your QT project directory, specify the path of the icon file in the code in the last sentence.
