Detailed Description

Definition at line 81 of file qwt_plot_abstract_canvas.h.

Member Typedef Documentation

typedef QFlags<PaintAttribute> QwtPlotAbstractGLCanvas::PaintAttributes

Paint attributes.

Definition at line 116 of file qwt_plot_abstract_canvas.h.

Member Enumeration Documentation

enum QwtPlotAbstractGLCanvas::PaintAttribute

Paint attributes.

The default setting enables BackingStore and Opaque.

See also

setPaintAttribute(), testPaintAttribute()

Enumerator
BackingStore	Paint double buffered reusing the content of the pixmap buffer when possible. Using a backing store might improve the performance significantly, when working with widget overlays ( like rubber bands ). Disabling the cache might improve the performance for incremental paints (using QwtPlotDirectPainter ). See also backingStore(), invalidateBackingStore()
ImmediatePaint	When ImmediatePaint is set replot() calls repaint() instead of update(). See also replot(), QWidget::repaint(), QWidget::update()
