 Create file filters suitable for use with QFileDialog.
 
QString QgsGuiUtils::createFileFilter_ (QString const &longName, QString const &glob)
 Convenience function for readily creating file filters.
 
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.
 
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.
 
QFont QgsGuiUtils::getFont (bool &ok, const QFont &initial, const QString &title=QString())
 Show font selection dialog.
 
QPair< QString, QString > GUI_EXPORT QgsGuiUtils::getSaveAsImageName (QWidget *parent, const QString &message, const QString &defaultFilename=QString())
 A helper function to get an image name from the user.
 
QSize QgsGuiUtils::iconSize (bool dockableToolbar=false)
 Returns the user-preferred size of a window's toolbar icons.
 
bool GUI_EXPORT QgsGuiUtils::openFilesRememberingFilter (QString const &filterName, QString const &filters, QStringList &selectedFiles, QString &enc, QString &title, bool cancelAll=false)
 Open files, preferring to have the default file selector be the last one used, if any; also, prefer to start in the last directory associated with filterName.
 
QSize QgsGuiUtils::panelIconSize (QSize size)

bool QgsGuiUtils::restoreGeometry (QWidget *widget, const QString &keyName=QString())
 Restore the wigget geometry from settings.
 
void QgsGuiUtils::saveGeometry (QWidget *widget, const QString &keyName=QString())
 Save the wigget geometry into settings.
 
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.
 
int QgsGuiUtils::significantDigits (const Qgis::DataType rasterDataType)
 Returns the maximum number of significant digits a for the given rasterDataType.
