[Maya-Python] mousePressEvent for swatchDisplayPort

[Risto Jankkila]

Hi,

I'm trying to execute a function when user clicks a swatchDisplayPort that's inside a Qt-window.

Currently my code looks something like this:

swatch_name = cmds.swatchDisplayPort(rs=64, wh=[64, 64], sn="lambert1")

ptr = OpenMayaUI.MQtUtil.findControl(swatch_name)

swatch_widget = shiboken.wrapInstance(long(ptr), QtGui.QWidget)

swatch_widget.mousePressEvent = my_func

I can get this to work on other Qt-objects (ie. labels) but not with swatchDisplayPorts.

Any help would be greatly appreciated.

Cheers,

Risto

Hi Risto,

What is "my_func"?

Hi Marcus,

"my_func" would be any function I would like to use to override mousePressEvent-method.

My colleague pointed out that event filters are a better way of doing this sort of thing, but I still wonder why this doesn't work with swatchDisplayPorts.

Cheers,
Risto

It may be that there are widgets on top of the widget you are monkey-patching that intercepts and accepts press events before it reaches your custom function.

You're probably right. Also shows why it was such a bad idea in the first place.

Thanks Marcus.

You can try running a QWidget.childAt(x, y) on the top-level widget to find out which widget will be receiving your mousePress'es first. That's the one you want to monkey-patch.
