[SOLVED] CSS change property from SLOT not working
-
Hi, I need to apply a CSS rule to my QSlider using properties but I am not able to do it in a SLOT (where I need to do it!) however I can do it in another function (called from the constructor).
This is where I set my CSS (in the constructor):
@this->setStyleSheet("QWidget{background:rgba(246,246,246,246);}""QSlider{background: transparent; width: 50px; height:20px; border-radius: 10px}" "::groove:horizontal {" "height: 20px;" "border-radius:10px;" "}" "::handle:horizontal {" " background: rgb(245,246,248);" " border: 1px solid rgb(220,220,220);" "height: 20px;" " width: 20px;" " border-radius: 10px;" "}" "::add-page:horizontal {" "background: rgb(212,212,212);" "height: 20px;" "border-top-right-radius: 10px;" "border-bottom-right-radius: 10px;" "}" "::sub-page:horizontal[state=\"false\"]{" "background: rgb(251,165,0);" "border-top-left-radius: 10px;" "border-bottom-left-radius: 10px;" "}" "::sub-page:horizontal[state=\"true\"]{" "background: red;" "border-top-left-radius: 10px;" "border-bottom-left-radius: 10px;" "}" );@
and this is what I do in my slot:
@ ui.slider1->setProperty("state", true);
ui.slider2->setProperty("state", true);
ui.slider3->setProperty("state", false);@I need to apply the "state" property in the slot but it is ignored while the other properties are applied correctly.
Can anyone help me?
Thanks a lot

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 ?
-
How should I initialize it?
-
That's up to you know what is a sensible default value. Probably false ?
-
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
