layout's widget does not autofit to window.

[Niamita]

Hi everyone

When i run my program on tablet, the layout of the window does not autofit to the tablet screen.
Layout does not get enlarge or shrink, while on pc it is fine as desire. I set the layou's widget size by setMinimumSize() in the ratio of device's screen width or height. i also tried to solve this by setting sizepolicy() but i does not get desire output on tablet.

One more think shall i have to set widget's stylesheet according to the screen resolution individualy.
Please help me, i am working on this since 1 and half day, but i am not successfull in getting the desire display on tablet.

are you talking about internal layout of widgets in your window or the window itself. For the latter case, have you tried showFullScreen(), showMaximised()?

i am talking about internal layout in window.

well it works for me on desktop. what happens of tablet? does it fills the entire screen or some part of it? how do you resize it on tablet?

[Niamita]

i am not resizing it on tablet, when i run it on tablet the layout does not fit to tablet screen, some part of designed layout get cut.

[nish]

Looks like the problem is due to the top buttons. They need that much size because of the text they have to display.

[Niamita]

So what i have to do then.

[nish]

there can be several ways, but all involve redesigning UI.
for example, make them as tabs.
or put the whole thing in a QScrollArea.

[Niamita]

Ya this can solve problem, but i have to design ui in the same manner in which i had.Is there any solution then.

[nish]

99% of the apps i have seen have different UIs on small screen devices than on desktop.
