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()
