Detailed Description

Instances of this class hold user defined rColors. They are displayed using the current settings for hue, saturation, value, and alpha. For the latter to be visible, the color is painted on a white background containing the greek letters "αΑα". The frames may be left clicked in order to emit the signal historySelected( curColor ). The same can be done with the right button down and selecting the "use color" item of the popup menu. The "delete color" entry of the same menu emits the signal deleteColor( this ).

Constructor & Destructor Documentation

HistoryFrame::HistoryFrame (  QWidget *  parent = 0, const char *  name = 0, WFlags  f = 0 )

The c'tor creates the frame and sets the current color to opaque white. The popup menu is initialized and connected here too. Here is the call graph for this function:

Member Function Documentation

void HistoryFrame::delColor (   )  [inline, slot]

void HistoryFrame::deleteColor (  HistoryFrame *   )  [signal]

const rColor& HistoryFrame::getColor (   )  [inline]

void HistoryFrame::historySelected (  const rColor &   )  [signal]

void HistoryFrame::mouseReleaseEvent (  QMouseEvent *  e  )  [protected]

Reimplemented from QFrame. We assume here that a mouse button must have been clicked: Why else could we get a release event? Anyway, if it was the left button coming up we emit the signal historySelected(). This will work on every instance, allowing the selection of opaque white. The right button however is ignored if the current color is opaque white. If it isn't, we will pop up the popper and let it take over from here.

void HistoryFrame::resizeEvent (  QResizeEvent *   )  [protected]

The resizeEvent is reimplemented from QFrame. This is necessary to adapt the sizes of our pixmaps to the new geometry. To conclude this, we do a setColor() to enforce a repaint of the frame contents. Here is the call graph for this function:

void HistoryFrame::setColor (  const rColor &  c  )

Sets the current color to c. The background pixmap is freshly painted and applied to the widget. Here is the call graph for this function:

void HistoryFrame::useColor (   )  [inline, slot]
