Hi there,

Just want to address this issue here before I file a bug. Whenever I run a script with a custom UI two times in quick succession, Clarisse 5 crashes. Same applies when I run two different scripts with UIs. I don't remember having those problems in v4, but it's 100% reproducible and 200% annoying.

Is there perhaps something I'm missing here, e.g. a destroyer command in the EventRewire class or anything else? The only way I know to destroy a window is this one after calling EventRewire:

Code: Select all

window.show()
while window.is_shown(): ix.application.check_for_events()
window.destroy()

Not sure if the error message helps here, but I think it's not very specific:

Code: Select all

Thx!

Seems I was able to find the issue: it was obviously not a related to the UI, but to an error inside a try-except routine.Sorry for the alarm, but it was really extremely annoying. Anyway, I'm hoping that was really the reason for all those crashes I had

No worries! Don't hesitate if you stumble on a real Python issue.

Will do!

Seems I was cheering to early... At least I was able to boil the problem down to the basic script below. To make Clarisse crash you only have to load the script to an empty scene and execute it several times. Sometimes it'll crash after the 2nd run, sometimes it takes 10+ runs, but in the end Clarisse will definitely crash. The code structure is from a v4 script and is used on a Windows 10 machine.

Thanks for any help!

Code: Select all

class EventRewire(ix.api.EventObject):

    def cancel(self, sender, evtid):
        sender.get_window().hide()

        print("Script cancelled.")

    def run(self, sender, evtid):

        sender.get_window().hide()

        self.inp1 = in1.get_value()
        self.inp2 = in2.get_value()
        self.inp3 = in3.get_value()

# ----- Draw the window

clarisse_win = ix.application.get_event_window()
window = ix.api.GuiWindow(clarisse_win, 900, 400, 500, 200)
window.set_title("Crash on Demand")

panel = ix.api.GuiPanel(window, 0, 0, window.get_width(), window.get_height())
panel.set_constraints(ix.api.GuiWidget.CONSTRAINT_LEFT, ix.api.GuiWidget.CONSTRAINT_TOP,
                      ix.api.GuiWidget.CONSTRAINT_RIGHT, ix.api.GuiWidget.CONSTRAINT_BOTTOM)

label1 = ix.api.GuiLabel(panel, 20, 20, 100, 20, "Value 1")
label2 = ix.api.GuiLabel(panel, 100, 20, 100, 20, "Value 2")
label3 = ix.api.GuiLabel(panel, 180, 20, 100, 20, "Value 3")

in1 = ix.api.GuiNumberField(panel, 20, 60, 50, "")
in2 = ix.api.GuiNumberField(panel, 100, 60, 50, "")
in3 = ix.api.GuiNumberField(panel, 180, 60, 50, "")

in1.set_value(1)
in2.set_value(2)
in3.set_value(3)

run_button= ix.api.GuiPushButton(panel, 20, 120, 100, 25, "OK")
cancel_button = ix.api.GuiPushButton(panel, 200, 120, 100, 25, "Cancel")

event_rewire = EventRewire()
event_rewire.connect(run_button, 'EVT_ID_PUSH_BUTTON_CLICK', event_rewire.run)
event_rewire.connect(cancel_button, 'EVT_ID_PUSH_BUTTON_CLICK', event_rewire.cancel)

window.show()

while window.is_shown():
    ix.application.check_for_events()

window.destroy()

I've reproduced the crash on my side. Would you my mind creating a bug report for proper tracking?
Thanks for the script.

Thanks so much for checking the script so quickly. Glad to hear that you're able to reproduce the error! And, yes, I'll create a bug report, of course.

Bug report is done

Thanks!
