As opposed to a normal command + button, a tool button usually doesn't show a text label, but shows + an icon instead. Its classic usage is to select tools, for example + the "pen" tool in a drawing program. This would be implemented + with a TQToolButton as toggle button (see setToggleButton() ). + + TQToolButton supports auto-raising. In auto-raise mode, the button + draws a 3D frame only when the mouse points at it. The feature is + automatically turned on when a button is used inside a TQToolBar. + Change it with setAutoRaise(). + + A tool button's icon is set as TQIconSet. This makes it possible to + specify different pixmaps for the disabled and active state. The + disabled pixmap is used when the button's functionality is not + available. The active pixmap is displayed when the button is + auto-raised because the mouse pointer is hovering over it. + + The button's look and dimension is adjustable with + setUsesBigPixmap() and setUsesTextLabel(). When used inside a + TQToolBar in a TQMainWindow, the button automatically adjusts to + TQMainWindow's settings (see TQMainWindow::setUsesTextLabel() and + TQMainWindow::setUsesBigPixmaps()). The pixmap set on a TQToolButton + will be set to 22x22 if it is bigger than this size. If + usesBigPixmap() is TRUE, then the pixmap will be set to 32x32. + + A tool button can offer additional choices in a popup menu. The + feature is sometimes used with the "Back" button in a web browser. + After pressing and holding the button down for a while, a menu + pops up showing a list of possible pages to jump to. With + TQToolButton you can set a popup menu using setPopup(). The default + delay is 600ms; you can adjust it with setPopupDelay(). + + \img qdockwindow.png Toolbar with Toolbuttons \caption A floating + TQToolbar with TQToolbuttons + + \sa TQPushButton TQToolBar TQMainWindow \link guibooks.html#fowler + GUI Design Handbook: Push Button\endlink +*/ + +/*! + \enum TQToolButton::TextPosition + + The position of the tool button's textLabel in relation to the + tool button's icon. + + \value BesideIcon The text appears beside the icon. + \value BelowIcon The text appears below the icon. +*/ + + +/*! + Constructs an empty tool button called \a name, with parent \a + parent. +*/ + +TQToolButton::TQToolButton( TQWidget * parent, const char *name ) + : TQButton( parent, name ) +{ + init(); +#ifndef TQT_NO_TOOLBAR + TQToolBar* tb = ::tqt_cast<TQToolBar*>(parent); + if ( tb ) { + setAutoRaise( TRUE ); + if ( tb->mainWindow() ) { + connect( tb->mainWindow(), TQ_SIGNAL(pixmapSizeChanged(bool)), + this, TQ_SLOT(setUsesBigPixmap(bool)) ); + setUsesBigPixmap( tb->mainWindow()->usesBigPixmaps() ); + connect( tb->mainWindow(), TQ_SIGNAL(usesTextLabelChanged(bool)), + this, TQ_SLOT(setUsesTextLabel(bool)) ); + setUsesTextLabel( tb->mainWindow()->usesTextLabel() ); + } else { + setUsesBigPixmap( FALSE ); + } + } else +#endif + { + setUsesBigPixmap( FALSE ); + } +} + + +/*! + Constructs a tool button as an arrow button.
