 Create file filters suitable for use with QFileDialog. More...
QString QgsGuiUtils::createFileFilter_ (QString const &longName, QString const &glob)
 Convenience function for readily creating file filters. More...
QString QgsGuiUtils::createWidgetKey (QWidget *widget, const QString &keyName=QString())
 Creates a key for the given widget that can be used to store related data in settings. More...
QString QgsGuiUtils::displayValueWithMaximumDecimals (const Qgis::DataType dataType, const double value, bool displayTrailingZeroes=false)
 Returns a localized string representation of the value with the appropriate number of decimals supported by the dataType. More...
QFont QgsGuiUtils::getFont (bool &ok, const QFont &initial, const QString &title=QString())
 Show font selection dialog. More...
QPair< QString, QString > GUI_EXPORT QgsGuiUtils::getSaveAsImageName (QWidget *parent, const QString &message, const QString &defaultFilename=QString())

int QgsGuiUtils::scaleIconSize (int standardSize)
 Scales an icon size to compensate for display pixel density, making the icon size hi-dpi friendly, whilst still resulting in pixel-perfect sizes for low-dpi displays. More...
int QgsGuiUtils::significantDigits (const Qgis::DataType rasterDataType)
 Returns the maximum number of significant digits a for the given rasterDataType. More...
