Problem with reffering to images (and another data files)

[kremuwa]

My Qt app folder looks like this:
- bin
- data

In 'bin' there is the .exe file, and in 'data' there is a folder called 'icons' and there are a lot of icons in PNG format.
All was great when I was running the exe file directly but when I started to run it using a shortcut on Desktop, there was no icons visible in the application.

Here is the way I'm reffering to those icons:

QAction *actionAddBox = new QAction(QIcon("../data/icons/addBox.png"),tr("Add new box (Ctrl+M)"),this);

QAction *actionAddBox = new QAction(QIcon("../data/icons/addBox.png"),tr("Add new box (Ctrl+M)"),this);

To copy to clipboard, switch view to plain text mode 

What should I do?

May be while starting the exe, its taking the desktop as the application directory. To confirm place data folder in desktop/../data and see what happens.
To resolve you better include the png as a resource. You wont have to worry about the paths.
Or make sure the relative paths are always there

Ok, with a little help I've found the solution. It was a matter of "Current Directory" (or "Starting Directory") - every shortcut has something like this, It should be set to /bin folder in my case.

Hey, but you've mentioned something about "including as a resource". How to do that? Can I include .dll files as well?

Read about The Qt Resource System

mingw32-make[1]: *** No rule to make target `application.qrc', needed by `release/qrc_application.cpp'. Stop.'

I'm having such a message when I'm trying to build the project.

You have to create a resource file (qrc extension) to embed your icon .

For example, create and name this file myresource.qrc, containing the following:

<RCC>
<qresource >
	<file>:/Image/myimage.png</file>
	<file>:/Image/otherimage.png</file>
</qresource>
</RCC>

<RCC>
<qresource >
	<file>:/Image/myimage.png</file>
	<file>:/Image/otherimage.png</file>
</qresource>
</RCC>

To copy to clipboard, switch view to plain text mode 

In your .pro file add the following: RESOURCES = myresource.qrc

Then run qmake and make in order to add your png to your app.

Yes, I have done it like this but now I'm reiceving a message from post #6. Thx Anyway.

What about if you run make clean ant then qmake and make ?

[kremuwa]

Oh, I'm a really stupid guy. I'm currently (temporarily) on computer with Windows and with option "hide popular extensions" on. I created new file, named it 'application.qrc' and thought it's all right. But it wasn't because this file has actually .txt extension . Thank you for your effort, sorry for my stupidity and lacks in knowledge of english. Works perfectly now .

Please, remove this post.

I've got another question.
Is there any way to merge dll files needed by my app, put them as a one file to the catalogue with the executable and make it work?
BTW. It would be even better if I could merge them with the executable itself. I tried doing so using the Qt Resource System, but i got messages like:

cc1plus.exe: out of memory allocating 65536 bytes

You have to use (or build) the static version of the libraries needed by your app and then add the name of those libraries (*.lib extension) to the list of libraries processed by the linker.
This process has got nothing to do with Qt resource files.
