pg.QtCore.QTimer callback function delayed

[kiran gopalan]

Hi,

I am using pg.QtCore.QTimer to update a grid of plots. I got help from this group to maximize a plot when clicked on it.

All theses plots are updated in realtime by the callback function for the QTimer.

When the window is showing full grid, the timer callbacl is not getting fired at the set time. But when I click on a sub-plot and maximize it, the timer callback fires properly.

I have confirmed that the callback function's processing time is less that the timer period and it is same when the window is in grid mode and maximized mode.

Anyone know why QTimer is behaving this way?

The processing time required to repaint the view is probably not included in your callback--usually the Qt event loop initiates repaints on its own.

Is there a workaround or an alterntive? Is using a third party timer (pyev) make it better? Or this has nothing to do with the timer?

I don't think the timer is the issue; most likely the combination of your callback and the repaint are longer than the timer interval.
