Use uic.loadUi and get mouseMoveEvent

[Mikeeeeee]

Hi!
I use

class MainWindow(QMainWindow): 
    def __init__(self): 
        super(MainWindow, self).__init__()
        self.ui = uic.loadUi("mainWindow.ui")

How I can get mouseMoveEvent from "mainWindow.ui"?

@Mikeeeeee
Override mouseMoveEvent(). Or install an event filter via installEventFilter().

Or install an event filter via installEventFilter().

Please give an example of how to do this

[jsulm]

@Mikeeeeee There are enough examples in Qt documentation.

There is no installEventFilter in this example

[jsulm]

@Mikeeeeee There is example for mouseMoveEvent
But I again did the search for you (no idea why you can't): https://doc.qt.io/qt-5/qobject.html#installEventFilter

I saw it.
It is not work:

self.installEventFilter(self.ui)

    def eventFilter(self, object, event):
        print(111111111111111)

[jsulm]

@Mikeeeeee said in Use uic.loadUi and get mouseMoveEvent:

self.ui

this is not an event filter...

[Mikeeeeee]

How do I get the events from the self.ui?

[jsulm]

@Mikeeeeee Install event filter there, probably like (I don't use Qt with Python):

self.ui.installEventFilter(myEventFilter)

where myEventFilter is your event filter object (like keyPressEater in the example).

@jsulm said in Use uic.loadUi and get mouseMoveEvent:

lf.ui.installEventFilter(myEventFilter)

Documentation:
void QObject::installEventFilter(QObject *filterObj)
Installs an event filter filterObj on this object. For example:

monitoredObj->installEventFilter(filterObj);

Your code will not work, you need to put an object in the function argument. I still need an example.

[jsulm]

@Mikeeeeee said in Use uic.loadUi and get mouseMoveEvent:

our code will not work, you need to put an object in the function argument.

That's exactly what I'm doing:

self.ui.installEventFilter(myEventFilter)

I even wrote: "where myEventFilter is your event filter object"!
So, why do you think it will not work? Did you try? I have no idea what other example you need, I'm out of this thread...

[Mikeeeeee]

@jsulm said in Use uic.loadUi and get mouseMoveEvent:

myEventFilter

I don't understand you. Please give a full-fledged example.

[Mikeeeeee]

It is work

self.ui.installEventFilter(self)

[jsulm]

I will not.

class MyEventFilter(QObject):
    def eventFilter(QObject obj, QEvent event):
        print("HERE")
        return QObject::eventFilter(obj, event)
...

myEventFilter = MyEventFilter()
self.ui.installEventFilter(myEventFilter)
