Background

This module allows you to control the" " appearance of the virtual desktops. KDE offers a variety of options" " for customization, including the ability to specify different settings" " for each virtual desktop, or a common background for all of them.

" " The appearance of the desktop results from the combination of its" " background colors and patterns, and optionally, wallpaper, which is" " based on the image from a graphic file.

" " The background can be made up of a single color, or a pair of colors" " which can be blended in a variety of patterns. Wallpaper is also" " customizable, with options for tiling and stretching images. The" " wallpaper can be overlaid opaquely, or blended in different ways with" " the background colors and patterns.

" " KDE allows you to have the wallpaper change automatically at specified" " intervals of time. You can also replace the background with a program" " that updates the desktop dynamically. For example, the \"kdeworld\"" " program shows a day/night map of the world which is updated periodically."); } void BGDialog::slotIdentifyScreens() { // Taken from PositionTab::showIdentify in kdebase/kcontrol/kicker/positiontab_impl.cpp for(unsigned s = 0; s < m_numScreens; s++) { QLabel *screenLabel = new QLabel(0,"Screen Identify", WDestructiveClose | WStyle_Customize | WX11BypassWM); QFont identifyFont(KGlobalSettings::generalFont()); identifyFont.setPixelSize(100); screenLabel->setFont(identifyFont); screenLabel->setFrameStyle(QFrame::Panel); screenLabel->setFrameShadow(QFrame::Plain); screenLabel->setAlignment(Qt::AlignCenter); screenLabel->setNum(int(s + 1)); // BUGLET: we should not allow the identification to be entered again // until the timer fires.
