Pdf viewer using QDesktopServices
-
Desktop Environment: KDE, Gnome, LXDE etc…
The file type/program association is not something that is automagical, your desktop environment has settings where this information is stored so when you double click on a document/media/whatever it opens one application. QDesktopEnvironment uses these services when available.For viewing PDFs, you need to use an external library like poppler
-
Yes I have Gnome Desktop environment.
When I double click on the document, it opens with application also. Still when I run the application that statement pops up. -
Not on your target, otherwise you wouldn't be using QWS
-
On my target itself I have gnome running.
When I double click on the pdf it opens using evince application. -
Then if your target is running Gnome, why do you use Qt for Embedded Linux ?
-
I want to run a Qt application, that opens pdf while I am running the application.
-
That point is clear. My question is why don't you use a standard Qt, since you already have Gnome running on your target ?
-
I don't want Qt to be installed on the target, so I have used Qt for embedded linux.
-
Qt for Embedded Linux doesn't mean it won't get installed. It means that you can use Qt without a display server like Xorg
-
Yes I understood that.
But I need to open a pdf how do I do that? -
Have a look at poppler
