CSS Styling for QwtPlotGrid line color (how?)

[alketi]

Following the CSS examples, I have color styling working for all the area of the plot I care about *except* the grid line color. Thank you Uwe.

I'm using a dark canvas background, so I need to be able to change the grid lines from their default black to a light gray, and (preferably) control their transparency.

I've tried a number of different ways to get this working, but haven't been successful and didn't see it in the examples.

I need this last piece to give the user control of the plot style with CSS!

Please tell the me the grid lines can be styled with CSS.

Qt stylesheets is by design a very limited concept - there is not even an idea how to extend it for third party widgets like Qwt. But what you can do is to introduce additional properties - or use the palette of the canvas for the grid colors.

I can see how to set dynamic properties in the code; for example, to set an error state for a text box, and then grab that property in the CSS and style it.

But, on the CSS-side, I can't figure out how to talk to the grid color, so attaching a property doesn't seem to help me.

Can you explain a bit more or post a short example?

Thanks Uwe.

Somehow like below:

class YourPlot: plublic QwtPlot
{
    Q_OBJECT
    Q_PROPERTY( QBrush gridColor READ gridColor WRITE setGridColor )
 
    ....
 
};

class YourPlot: plublic QwtPlot
{
    Q_OBJECT
    Q_PROPERTY( QBrush gridColor READ gridColor WRITE setGridColor )

    ....

};

To copy to clipboard, switch view to plain text mode 

YourPlot {
    qproperty-gridColor: ...;
}

YourPlot {
    qproperty-gridColor: ...;
}

To copy to clipboard, switch view to plain text mode 

Instead you could also use colors from the canvas palette, that are not in use.
