Member Function Documentation

ImageSelectorDialog::ImageSelectorDialog ( QWidget * parent = 0, const char * name = 0, bool modal = TRUE, const QString & srcdir = QString::null, int wflags = 0 )

parent, name, modal, and wflags are the standard Qt QDialog flags. srcdir refers to base directory where images may be located. By default, this is QString::null, referring to the Qtopia Documents area. If you require access to a particular directory, specify the path.

Example:

    QString directory = QPEApplication::qpeDir() + "pics/wallpaper";
    ImageSelectorDialog *is = new ImageSelectorDialog(this, "Wallpapers", TRUE, directory);
