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 = ::tqqt_cast<TQToolBar*>(parent); - if ( tb ) { - setAutoRaise( TRUE ); - if ( tb->mainWindow() ) { - connect( tb->mainWindow(), TQT_SIGNAL(pixmapSizeChanged(bool)), - this, TQT_SLOT(setUsesBigPixmap(bool)) ); - setUsesBigPixmap( tb->mainWindow()->usesBigPixmaps() ); - connect( tb->mainWindow(), TQT_SIGNAL(usesTextLabelChanged(bool)), - this, TQT_SLOT(setUsesTextLabel(bool)) ); - setUsesTextLabel( tb->mainWindow()->usesTextLabel() ); - } else { - setUsesBigPixmap( FALSE ); - } - } else -#endif - { - setUsesBigPixmap( FALSE ); - } -} - - -/*! - Constructs a tool button as an arrow button.
