Detailed Description

/namespace QgisGui The QgisGui namespace contains constants and helper functions used throughout the QGIS GUI.

Function Documentation

QString QgisGui::createFileFilter_	(	QString const &	longName,
		QString const &	glob
	)

Convenience function for readily creating file filters.

Given a long name for a file filter and a regular expression, return a file filter string suitable for use in a QFileDialog::OpenFiles() call. The regular express, glob, will have both all lower and upper case versions added.

QPair< QString, QString > GUI_EXPORT QgisGui::getSaveAsImageName	(	QWidget *	theParent,
		QString	theMessage,
		QString	defaultFilename = QString::null
	)

A helper function to get an image name from the user.

It will nicely provide filters with all available writable image formats.

Parameters

theParent	widget that should act as the parent for the file dialog
theMessage	the message to display to the user
defaultFilename	default file name (empty by default)

Returns

QPair<QString, QString> where first is the file name and second is the file type

bool GUI_EXPORT QgisGui::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.

Parameters

filterName	the name of the filter; used for persistent store key
filters	the file filters used for QFileDialog
selectedFiles	string list of selected files; will be empty if none selected
enc	encoding?
title	the title for the dialog
cancelAll	add button to cancel further requests

Note

Stores persistent settings under /UI/. The sub-keys will be filterName and filterName + "Dir".

Opens dialog on last directory associated with the filter name, or the current working directory if this is the first time invoked with the current filter name.

This method returns true if cancel all was clicked, otherwise false

Variable Documentation

const Qt::WFlags QgisGui::ModalDialogFlags = 0

static

/var ModalDialogFlags /brief Flags used to create a modal dialog (adapted from QMessageBox).

Using these flags for all modal dialogs throughout QGIS ensures that for platforms such as the Mac where modal and modeless dialogs have different looks, QGIS modal dialogs will look the same as Qt modal dialogs and all modal dialogs will look distinct from modeless dialogs. Althought not the standard Mac modal look, it does lack the minimize control which makes sense only for modeless dislogs.

The Qt3 method of creating a true Mac modal dialog is deprecated in Qt4 and should not be used due to conflicts with QMessageBox style dialogs.

Qt::WindowMaximizeButtonHint is included but will be ignored if the dialog is a fixed size and does not have a size grip.
