Add Application Icon without PRO file?

[grantbj74]

Hi,

My Windows and Linux application doesn't use a QT project file to compile.

Is it still possible to link a resource file ?

Maybe I need to add resource entry to my makefile instead ?

Think i'm using the borland compiler to make it.

Can anyone help ?

Thanks
Brendan

You are right, you need to make entry in Makefile. Because .pro file is the upper level of Makefile itself.
QMake converts .pro file into Makefile.

Thanks, do you know how I do this ?

I tried both of the following in the makefile declarations:

RC_FILE = myapp.rc
 
RESOURCE = myapp.qrc

RC_FILE = myapp.rc

RESOURCE = myapp.qrc

To copy to clipboard, switch view to plain text mode 

I tried this in the main.cpp:

QApplication::setWindowIcon(QIcon(":/images/blue.png"));

QApplication::setWindowIcon(QIcon(":/images/blue.png"));

To copy to clipboard, switch view to plain text mode 

This is one resource attempt (myapp.rc):

IDI_ICON1               ICON    DISCARDABLE     "blue.png"

IDI_ICON1               ICON    DISCARDABLE     "blue.png"

To copy to clipboard, switch view to plain text mode 

This is the other resource attempt (myapp.qrc):

<RCC>
  <qresource>
    <file>images/blue.png</file>
  </qresource>
</RCC>

<RCC>
  <qresource>
    <file>images/blue.png</file>
  </qresource>
</RCC>

All files are in the same folder.

I think you are mixing "application icon" and "window icon" terms and also "Windows resource file" and "Qt resource file" terms. And adding such pure statements into Makefile won't do anything, you need to write proper make rules to do that. RC_FILE and RESOURCES (not RESOURCE) are QMake statements.

As Wysota already said there is a difference in application icon and window icon:

Application Icon: The Icon visible on the application in an windows explorer or shortcut etc.
Window Icon: The icon visible on the top left MainWindow of your application (or dialogs or subwindows)

The Window Icon can be set with Widget::setWindowIcon or Application::setWindowIcon for top Left of main window.

The application can be set with: Set Application Icon

IDI_ICON1 ICON DISCARDABLE "blue.png"

Be sure to use an ICON format and not a PNG format!

Thanks,

Thats handy to know that there is a difference between application and window icon.

I'm going to try to get the application icon going first.

I'm compiling in cygwin with mingw32 compiler. It still doesn't seem to use the icon.

Tried both resource declarations individually in mk file, and the following line is the qtapp.rc file:

RC_FILE += qtapp.rc
RESOURCES += qtapp.rc
 
IDI_ICON1               ICON    DISCARDABLE     "qtapp.ico"

RC_FILE += qtapp.rc
RESOURCES += qtapp.rc

IDI_ICON1               ICON    DISCARDABLE     "qtapp.ico"

I guess I need to do this, how do you do this ?

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.

You place respective entries in your Makefile. Or you start thinking - "hey, maybe I should use QMake after all?".

Yeah I might start using qmake temporarilly.

Unfortunately the company I work for has an autobuilder, and this would be the only application requiring qmake, so probably won't happen.

To get the application icon working I did the following in the mk file (I copied it from a similar application) :

LDRES += \
    $(PROJECT)_res.o
 
$(PROJECT)_res.o: $(PROJECT).rc
	$(BRCC32)
 
$(PROJECT): $(PROJECT)_res.o

LDRES += \
    $(PROJECT)_res.o

$(PROJECT)_res.o: $(PROJECT).rc
	$(BRCC32)

$(PROJECT): $(PROJECT)_res.o
