Open multiple files with one program instance
Hi, I want to select multiple files in Windows explorer and open them (by pressing Enter) with the same program instance.
For now I can open one file this way, but if I select multiple files, I get the same number of instances of my program, and each of these instances opens one file.
Is there a way to achieve the "all files - one instance" goal with Qt mechanisms, or do I have to use a native API?
If the latter, any ideas for what I'd have to search? A short search brought "dde" up, is this right?
Thanks in advance,
Ginsengelf
Re: Open multiple files with one program instance
maybe I didn't understand properly what you need, but did you see QFileDialog::getOpenFileNames method?
Re: Open multiple files with one program instance
Have a look at QtSingeApplication and the article at the wiki (I think there was one...)
Re: Open multiple files with one program instance
I don't know the exact solution, but generally your problem splits in two sub problems:
A) Only open ine instance of your program at a time
B) give an open instance of you program an external command to open a certain file
DDE sounds good, I used this with Latex some time ago...

The QtSingleApplication looks like something I can use, thanks. In the wiki there's an just article about the Singleton pattern (or maybe I missed the correct one).

Indeed...:eek: it is listed under "Categories -> Tutorials" on the left, but I just looked over the wiki main page where it is not listed :confused:
