Solved Qt Opengl
How i can develop flight instrument in qt with opengl. ```
The first step would be to learn openGL.
Then check out Qt samples
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"?
Geographical information system.
if you mean sort of like this
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.
There are many sources of such data
Thanks sir, i think this will resolve my problem.
How to change image of pushbutton (clicked option not pressed option) i.e image change with clicked option.
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?
I want to make on/ off button. If i press on, button will remain in that state until i pressed again.
It can do that.
then button is like on/off
Then with stylesheet use the selectors
to change images.
Thanks its working now.
Can we make tristate swich using push button? On , off and intermediate state.
