Add color to ui backgroung

[Santosh Reddy]

right click on form -> change style sheet -> add gradient -> apply -> ok

right click on form -> change style sheet -> add gradient -> background-color - apply -> ok, also make sure QtDesigner should show the background color.

is there a way to change a label color dynamically like if some value is one label color will be read and other wise green

you can use setStyleSheet() in run time

thank u sir but

in question no 1 i have done this but by setting background will make my program to finish unexpectedly. my list box color dont cause any problem but back color of whole form cause problem

[Santosh Reddy]

by problem you mean application crash?
Then thumb rule: did you clean the project and compile?
Can you post the style-sheet from the Qt Designer?
Also did you check the stack, if crashing is your problem.

the whole background being black should not be a problem for functionality, it will be very hard to find list box in dark.

[maarvi]

yes sir my application crashes

i have clean and compile but no use

here the pink color of the the back ground when i remove it i working well but when when i add pink or anyother color its working fine .

[Santosh Reddy]

not sure what's the reason..., did you try look at the stack

[maarvi]

yes sir its giving me the error in ui->setupUI(this)

[Santosh Reddy]

delete the ui_xxxx.h file from the disk, and the build the program, it if does not solve, you have to debug the the ui_xxxx.h file stepping in, and see where it crashes...
