Proprietary stylesheet for a button in external stylesheet file

absfrm

Hi
I'm loading an external style sheet file for my form.
this is code :
@
QPushButton{
background: transparent;
color: white;
}

QPushButton QPushButton:on{
background: transparent;
color: white;
}
@

How can i set this style sheet for just one button with name btngo ?

DerManu

Try
@
qApp->findChild<QPushButton*>("btngo")->setStyleSheet("...style...");
@

If you have multiple "btngo"-buttons that should all have that stylesheet, use findChildren and iterate over the list.

absfrm

@
qApp->findChild<QPushButton*>("btngo")->setStyleSheet("QPushButton{background: transparent; color: white;}QPushButton QPushButton:pressed{background: transparent;color: white;}");
@
no work!

any way to explain it in style sheet file?

DerManu

Is the correct pointer returned by findChild? Does the styleSheet work when using it on the variable (i.e. ui->btngo->setStyleSheet or similar?

absfrm

No,i want to define it in .qss file in external style sheet

ui->btngo->setStyleSheet(); is working right

DerManu

So in this case
@
qApp->findChild<QPushButton*>("btngo")
@
seems to return the wrong button (or none at all). Is the button really called btngo? What's returned by ui->btngo->name()?
Further, try using the findChild not on qApp but on your main window (or the window which contains the button) instead.

//EDIT: Ah now I think I get it, you want to define inside the CSS file which button name to style, right? I don't know of a Qt-way to do that. Maybe you should parse the CSS file yourself and add some extended syntax which then uses the findChild function to apply it to a QWidget with the specified name.
