Hi
The first step would be to learn openGL.

Then I would think about if QML would be an option if for mobile.

Thanks, can we integrate tarrin database in qt with opengl. Also, is there any open source tarrin database is available?```

@mkss What is "tarrin database"?

Mkss

Geographical information system.

mrjj

Then yes, its possible
but as far as i know, Qt do not have special support for it so you would have to program it yourself.

Mkss

Thanks sir, i think this will resolve my problem.

Hello,
How to change image of pushbutton (clicked option not pressed option) i.e image change with clicked option.

mrjj

@mkss
Hi
why can't you use the pressed state?
When left mouse is held down, it will show the image. when released, it
will revert to the first one.

There is no state for "clicked"
and since a click is mouse press event and a release event, i don't understand
why pressed, is not usable for you?

@mrjj
Hi
I want to make on/ off button. If i press on, button will remain in that state until i pressed again.

mrjj

Then with stylesheet use the selectors
QPushButton {}
QPushButton:checked{}
to change images.

@mrjj
Thanks its working now.
