To - associate a cursor with all widgets (normally for a short period - of time), use TQApplication::setOverrideCursor(). - - To set a cursor tqshape use TQCursor::setShape() or use the TQCursor - constructor which takes the tqshape as argument, or you can use one - of the predefined cursors defined in the \l tqCursorShape enum. - - If you want to create a cursor with your own bitmap, either use - the TQCursor constructor which takes a bitmap and a mask or the - constructor which takes a pixmap as arguments. - - To set or get the position of the mouse cursor use the static - methods TQCursor::pos() and TQCursor::setPos(). - - \img cursors.png Cursor Shapes - - \sa TQWidget \link guibooks.html#fowler GUI Design Handbook: - Cursors\endlink - - On X11, TQt supports the \link - http://www.xfree86.org/4.3.0/Xcursor.3.html Xcursor\endlink - library, which allows for full color icon themes. The table below - shows the cursor name used for each TQt::tqCursorShape value. If a - cursor cannot be found using the name shown below, a standard X11 - cursor will be used instead. Note: X11 does not provide - appropriate cursors for all possible TQt::tqCursorShape values. It - is possible that some cursors will be taken from the Xcursor - theme, while others will use an internal bitmap cursor. - - \table - \header \i TQt::tqCursorShape Values \i Cursor Names - \row \i TQt::ArrowCursor \i left_ptr - \row \i TQt::UpArrowCursor \i up_arrow - \row \i TQt::CrossCursor \i cross - \row \i TQt::WaitCursor \i wait - \row \i TQt::BusyCursor \i left_ptr_watch - \row \i TQt::IbeamCursor \i ibeam - \row \i TQt::SizeVerCursor \i size_ver - \row \i TQt::SizeHorCursor \i size_hor - \row \i TQt::SizeBDiagCursor \i size_bdiag - \row \i TQt::SizeFDiagCursor \i size_fdiag - \row \i TQt::SizeAllCursor \i size_all - \row \i TQt::SplitVCursor \i split_v - \row \i TQt::SplitHCursor \i split_h - \row \i TQt::PointingHandCursor \i pointing_hand - \row \i TQt::ForbiddenCursor \i forbidden - \row \i TQt::WhatsThisCursor \i whats_this - \endtable -*/ - -/*! - \enum TQt::tqCursorShape - - This enum type defines the various cursors that can be used. - - \value ArrowCursor standard arrow cursor - \value UpArrowCursor upwards arrow - \value CrossCursor crosshair - \value WaitCursor hourglass/watch - \value BusyCursor standard arrow with hourglass/watch - \value IbeamCursor ibeam/text entry - \value SizeVerCursor vertical resize - \value SizeHorCursor horizontal resize - \value SizeFDiagCursor diagonal resize (\) - \value SizeBDiagCursor diagonal resize (/) - \value SizeAllCursor all directions resize - \value BlankCursor blank/invisible cursor - \value SplitVCursor vertical splitting - \value SplitHCursor horizontal splitting - \value PointingHandCursor a pointing hand - \value ForbiddenCursor a slashed circle - \value WhatsThisCursor an arrow with a question mark - \value BitmapCursor - - ArrowCursor is the default for widgets in a normal state. - - \img cursors.png Cursor Shapes -*/ - -/***************************************************************************** - TQCursor stream functions - *****************************************************************************/ - -#ifndef TQT_NO_DATASTREAM - - -/*! - \relates TQCursor - Writes the cursor \a c to the stream \a s. - - \sa \link datastreamformat.html Format of the TQDataStream operators \endlink -*/ - -TQDataStream &operator<<( TQDataStream &s, const TQCursor &c ) -{ - s << (TQ_INT16)c.tqshape(); // write tqshape id to stream - if ( c.tqshape() == TQt::BitmapCursor ) { // bitmap cursor -#if !defined(TQT_NO_IMAGEIO) - s << *c.bitmap() << *c.mask(); - s << c.hotSpot(); -#else - qWarning("No Image Cursor I/O"); -#endif - } - return s; -} - -/*! - \relates TQCursor - Reads a cursor from the stream \a s and sets \a c to the read data. - - \sa \link datastreamformat.html Format of the TQDataStream operators \endlink -*/ - -TQDataStream &operator>>( TQDataStream &s, TQCursor &c ) -{ - TQ_INT16 tqshape; - s >> tqshape; // read tqshape id from stream - if ( tqshape == TQt::BitmapCursor ) { // read bitmap cursor -#if !defined(TQT_NO_IMAGEIO) - TQBitmap bm, bmm; - TQPoint hot; - s >> bm >> bmm >> hot; - c = TQCursor( bm, bmm, hot.x(), hot.y() ); -#else - qWarning("No Image Cursor I/O"); -#endif - } else { - c.setShape( (int)tqshape ); // create cursor with tqshape - } - return s; -} -#endif // TQT_NO_DATASTREAM - - -/*! - Constructs a custom pixmap cursor. - - \a pixmap is the image.
