Qt Script - new angle ?

David King

Hi,

I'm using Qt Script only. In other words just a .js and .ui file.
This because Qt Script is all that our vendor custom-functions, support.
So no full blown Qt, for us :-/

I'm familiar with Qt Scripting such as the following, that updates the text in a label,
in response to changes to a dial:

var label = myDialog.findChild("label_Foo");
var dial = myDialog.findChild("dial_Foo");

dial.valueChanged.connect(label.setText);

My I ask though, if I've added a conical gradient to my label, via a stylesheet,
and want to call setAngle( ) of the gradient, in response to changes to the dial,
to whiz around the gradient, is that possible, from just Qt Script ?

Stumbling around a bit, I've tried the following.
Also same with : or :: or -> instead of . after the Foo.

var gradient = myDialog.findChild("label_Foo.QConicalGradient");
dial.valueChanged.connect(gradient.setAngle);

I've tried also the following.
Also same with : or :: or -> instead of . after the connect, each place.

var label = myDialog.findChild("label_Foo");
dial.valueChanged.connect(label.QConicalGradient.setAngle);

But all throw errors.
I'm sure not surprisingly given the comic element of some of the syntax I've been trying.

Best regards,

David

Hi,

And if I can't call setAngle, from Qt Script, then I'd settle just for dynamic change to a stylesheet.
Specifically, the angle number, below.
Or the whole stylesheet text, with just the angle number altered.

background-color: qconicalgradient(cx:0.5, cy:0.7, angle:90.0, stop:0.499 red, stop:0.5 grey);

Provided, dynamic change to a stylesheet, actually results in a change on-screen.
And reasonably good update rate.
I'd settle for 10 a second :-)

Best regards,

David
