|

QwtPlot is a composite widget consisting of a title label,
|
||||
the canvas, the scales and a legend. Although all components
|
||||
should be exchangable some day, the current design isn´t ready for it.
|
||||
|
||||
In this situation event filtering is the mechanism to extend the behaviour
|
||||
of the plot components. event_filter shows 3 examples how to use it:
|
||||
|
||||
1) CanvasPicker
|
||||
|
||||
The CanvasPicker implements a solution, how to move points on the canvas
|
||||
with mouse and keyboard.
|
||||
|
||||
2) ScalePicker
|
||||
|
||||
The ScalePicker translates the position of mouse clicks on the scales
|
||||
and emits them as signals.
|
||||
|
||||
3) Plot: ColorBar, QSlider
|
||||
|
||||
The Plot class shows how to add widgets to the scales. In this example
|
||||
there is no filter class. The derived plot widget filters its components.
|
||||
|
||||
|
||||
Please note that CanvasPicker and ScalePicker are standalone classes
|
||||
that could be connected with your QwtPlot as well.
