"""
|
|
Simple example of loading UI template created with Qt Designer.
|
|
|
|
This example uses uic.loadUiType to parse and load the ui at runtime. It is also
|
|
possible to pre-compile the .ui file using pyuic (see VideoSpeedTest and
|
|
ScatterPlotSpeedTest examples; these .ui files have been compiled with the
|
|
tools/rebuildUi.py script).
