This is an old revision of the document!
Append a regularly defined set of differently sized icon images to a QIcon.
theIcon is a pointer to the icon that will be built/appened to. iconRscTemplate is a string that provides a template for the icon resource. The tag %size% will be replaced by “{iconSize}x{iconSize}”, and %dim% by “{iconSize}” where {iconSize} is a string version of an element in sizeList. sizeList contains a list of single-dimension sizes to be added to the icon.
Example: Assuming the resources “:myIcons/16×16/exit.png”, “:myIcons/24×24/exit.png”, and “:myIcons/32×32/exit.png” are available.
QList<int> sizes; sizes << 16 << 24 << 32; QIcon exitIcon; buildIcon(&exitIcon, ":myIcons/%size%/exit.png", sizes);
buildIcon() does NOT check whether the referenced resources actually exist.
void MainWindow::buildIcon(QIcon* const theIcon, QString const &iconRscTemplate, QList const &sizeList) { foreach (const int iconSize in sizeList) { QString theResource = iconRscTemplate; theResource.replace(QString("%size%"), iconSize+"x"+iconSize); // does this work? theResource.replace(QString("%dim%"), iconSize+""); // does this work? theIcon->addFile(theResource, QSize(iconSize, iconSize)) } }
