Pdfedit and resources

[Martin P. <ma...@pe...>]

Considering "qt won't start without config file" problems:

I saw article:
https://www.abclinuxu.cz/clanky/programovani/graficke-programy-v-qt-4-7-lokalizace-a-data-programu

and I though of solution - some files (perhaps the main config file and 
maybe some/all icons and scripts) can be put into resources.

If we put up a resource file like:

<!DOCTYPE RCC><RCC version="1.0">
<qresource>
	<file>pdfeditrc</file>
	<file>icon/Tango/about.png</file>
         ....
</qresource>
</RCC>

Then add to pdfedit.pro something like this:

RESOURCES += resources.qrc

then the specified files would end up embedded in the binary, and we can 
access them like this:

QPixmap icon(":/icon/Tango/about.png");

QFile and QDir can be used too for reading(QFile)/enumerating(QDir) 
resources (http://doc.trolltech.com/4.5/resources.html)
So we'll just add the resource path ":/" to search path for icons and 
scripts and we can put these to resources, which will basically eliminate 
"main config file not found" bugs, since it would be embedded in the binary 
by the compiler (though i'll keep it so it would look in the "usual 
directories" first, so you can override these data files without having to 
recompile the binary)

What could be easily put up in resources and be used from there:
* Scripts. Icons. Main config file
What probably can't be put there (or at least it won't be easy to do):
* Translations. Help files	

Note that this resource system is Qt4 only - Qt3 does not have this mechanism.
So we can use it once qt4 will be complete.

Any thoughts/opinions?
