[SOLVED] CSS change property from SLOT not working

rfringuello89

Solved doing a first setProperty in the other method then it works in the slot!

Hi,

Since it's a static style sheet, why don't you apply it directly in the constructor ?

bq. This is where I set my CSS (in the constructor):
bq. this->setStyleSheet("QWidget{background:rgba(246,246,246,246);}"
bq. ......

As I said, I set the style sheet in the constructor while at runtime I set the correct "state" property. It works but I need to set the property twice in order to see it applied like:
@ ui.slider1->setProperty("state", true);
ui.slider1->setProperty("state", true);

Sorry, I missed the parenthesis about the constructor.

Do you initialize the state property ?

rfringuello89

How should I initialize it?

SGaist

That's up to you know what is a sensible default value. Probably false ?

rfringuello89

Oh sure! I didn't understand what you meant!
Yes I am initializing it in an init() method called by the constructor!

@ui.slider1->setProperty("state", false);@

I thought I was forgetting something… "Here":http://qt-project.org/wiki/DynamicPropertiesAndStylesheets you have the technique

Well, I solved the problem. I was using that post to learn how to do it but I wasn't doing this:
@tstFrame->setProperty("error",true);
tstFrame->style()->unpolish(tstFrame);
tstFrame->style()->polish(tstFrame);
tstFrame->update();@

because when I started this thread I tried that piece of code but I had many errors (I don't remember which ones) and I thought it was for older versions of QT :(

Thanks :D
