Porting a GUI from Qt 2(?)

[MScottM]

I'm hoping this is the right place to ask...

I've been trying to get a program written back in 2001 to work in Qt6.

My project files are here: github

I'm treating this as a learning exercise, but also hope to end up with a useful (to me) piece of software if I can make it work.

I'm at a point where I'm trying to figure out the GUI. It looks like the author used some kind of ASCII graphics (in a file called qtpcr.xpm), and QCanvas. I'm hoping someone with GUI experience would be willing to scan through the files and tell me if there is a good way forward with this - QGraphicsView, QML, or ? I've been reading up on the QGraphicsView framework, and I admit its a steep learning curve for me, but if this is the proper method, I'll keep at it.

Hi,

From a really quick look, there's no need for a change of technology. The xpm file is used to create a QPixmap.

Can you explain the issue you have ?
I don't have a machine at hand to try and build the project but from my light overview I did not see anything really exotic.

The long way would be:

• Qt 3 port
• Qt 4 port
• Qt 5 port
• Qt 6 corrections

You likely won't need so many steps as it seems the application uses pretty standard widgets.

Hi @SGaist,

Thanks for the feedback. Right now I'm working with the scanDialog code, trying to figure out how to port it from QCanvas.

Can you expand a bit on what you mean when you say 'the long way'?

@MScottM
He just means the "long way" would be to go through each of these 4 ports/upgrades in sequence. But in practice if your code is straightforward you should be able to skip doing each one individually, e.g. you might manage 2 to 4 in one go and 4 to 6 in another go.

@JonB,

Ah - okay, I get it.

I did some looking around and found this page and I'm starting with that. Would issues I'm having best be addressed in 'General and Desktop'?

[SGaist]

Yes, that would the the correct sub-forum.
