Passing variable to stylesheet in runtime

[ndev]

Hi,
is it possible to pass variable from application to stylesheet in runtime ?
For example, set background image for button:
QPushButton{
background-image: buttonImage;
background-repeat: no-repeat;
background-position: left;
}
where buttonImage is set like setProperty("buttonImage", "url(:/down.png)");

There is some ability to use dynamic properties to change styles on-the-fly
http://qt-project.org/wiki/DynamicPr...AndStylesheets

This approach may not be suited to arbitrary changes like the one you are after. If you are trying to change the image on the button based on whether it is pushed/not-pushed on/off etc then you should look at the QIcon class ability to hold multiple images for different states.

I know about property selector, but I need more advanced control to use different images for buttons in runtime.
QIcon doesn't fit because I'd like to place image on left button side, not on center. Also I need at least 2 states: default and hover.

Have you considered using a custom style instead of stylesheets?

Will this help

QPushButton button;
 
QString styleSheetTemplate = "QPushButton {"
                             "background-image: %1;"
                             "background-repeat: no-repeat;"
                             "background-position: left;"
                             "}";
 
button.setProperty("buttonImage", "url(:/down)");
 
QString styleSheet = styleSheetTemplate.arg(button.property("buttonImage").toString());
 
button.setStyleSheet(styleSheet);

QPushButton button;

QString styleSheetTemplate = "QPushButton {"
                             "background-image: %1;"
                             "background-repeat: no-repeat;"
                             "background-position: left;"
                             "}";

button.setProperty("buttonImage", "url(:/down)");

QString styleSheet = styleSheetTemplate.arg(button.property("buttonImage").toString());

button.setStyleSheet(styleSheet);

To copy to clipboard, switch view to plain text mode

Main idea was to have only one stylesheet for whole application with ability to change some values dynamically, but as I see currently this isn't possible.
So, I've made workaround, by overriding stylesheet for button with custom background-image property.
