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.
