How to use matchbox and Qt together?

rajeev - March 16, 2011

Hi,

I would like to know how to use Qt and matchbox together. I have compiled Qt with frame bufffer support and matchbox is running on X server. It is working but some painting issues are coming. When we are trying to select a particular icon in Qt application, the match box desktop is responding, especially when some timer is running on Qt application

Regards,

Rajeev N Sambhu

Hi Rajeev,

Sorry for the late reply. Can you provide more information about your problem? Specifically, what do you mean by "painting issues"? What do you mean by "some timer is running on Qt application"?

Thanks

Bill

surprised you got it to work

Hi rajeev,

I'm surprised that you got this to work: you have two applications that both want access to the screen - so there will always be issues like repainting and stealing of events (keyboard/touchscreen) unless you take specifically good care.

There is an x11 version of QT that will work nicely along with matchbox and will not have repainting issues.

Choose to build X11 kdrive - that will bypass the remoting frameworks in X.
Let X11 handle all framebuffer access and the abstraction of keyboards/mice/touchscreens.

Qt works very well with X11 - as matter of fact it was first on X11, only then the framebuffer version came along. Qt is the base of e.g. the KDE desktop, Photoshop Elements and either Picasa or Google Earth (I forgot which one).
