I have somewhat similar problem. I did the original layout in designer and re-wrote in straight Qt. i have program generated data that I store in sub-directories

Source code

 
1
2

	k = QDir::currentDirPath();                         
	k.append( "/jobs/" + projectIndex + "/" + f );
I can copy the parent directory along with all the sub-directories to another directory and run the program in a terminal and all is fine, but if I run it from a "konqueror" window, the program run ok, but the program does not see the data in the sub-directories. Is this the same problem? I have copied the sub-directories as you suggested.

If you add "IMAGES += img1.png ... imgn.png" to your .pro file, qmake will create an image collection that will be compiled into your executable. To access these images you can use QPixmap::fromMimeSource() method.

In Qt4 you can use resource files.

Similar, you are using the QDir::currentDirPath() method and current dir can be any path in the system --- it just points to the directory from which user has started your program. Try using QApplication::applicationDirPath().

Yes. qmake will do everything for you, just remember about using QPixmap::fromMimeSource().

It is important to use QPixmap::fromMimeSource() ??

You will give them ;) Only they will be hidden inside your executable --- you won't need any additional files.

You will have to retrieve those icons from the image collection and that's what this method does.

Suppose you have img1.png in the image collection, to get it and use in your program your need this:

Source code

 
1

QPixmap pixmap = QPixmap::fromMimeSource("img1.png");

this was generated by the designer:

Quoted


next_btn = new QPushButton( navegator_gb, "next_btn" );
next_btn->setGeometry( QRect( 270, 16, 24, 24 ) );
next_btn->setIconSet( QIconSet( QPixmap::fromMimeSource( "rightarrow.png" ) ) );

Thanks Jacek.
I don't know how to implement your suggestion

Source code

 
1

QApplication::applicationDirPath().
I put <,application.h> in my "dlgmain.cpp" file and changed code as follows

Source code

 
1
2
3

	k = QApplication::applicationDirPath();
	//k = QDir::currentDirPath();                         
	k.append( "/jobs/" + projectIndex + "/" + f );
and got the error message

Source code

dlgmain.cpp:905: error: cannot call member function `QString QApplication::applicationDirPath()' without object
I then put

Source code

 
1

QApplication myApp = new QApplication( this );
in the "dlgmain.cpp" constructor and revised the code to

Source code

2
3

	k = myApp.applicationDirPath();
	//k = QDir::currentDirPath();                         
	k.append( "/jobs/" + projectIndex + "/" + f );
and my error was

ObviouslyI don't know how to implement your suggestion. Do I have to place it in "main.cpp" and to be able to use it in "dlgmain.cpp" and other ".cpp" files? If so what would be the code? This problem has been bothering me for a long time and Marioo's thread got my attention. (Thanks Marioo)

You could start by reading the docs to see what QApplication parameters are and that you have a global pointer to your QApplication object called qApp, so you should be using qApp->applicationDirPath().

QApplication::applicationDirPath is not static.
While this notation inside code is usually used for static methods, it is also used in emails or other text conversation media to fully specify a method, i.e. which class it belongs and what it is named.

It is assumed that the read has access to the API docs and can lookup static'ness themselves.

Thanks myota. I shall reall read the Docs more careful in the future, but you have solved my problem!! I copied the sub-directories that carried the generated data and the executable to o "flash" drive. Ran like it should. Again thank you.
