TCanvas::Closed() not emitted when closing window

[OSchaile]

Hi,
I guess this is connected to this:

TCanvas is not recreated in ROOT 6.10/00

Hello, it seems there is a regression in ROOT 6.10/00.If I created a TH1 and I plot it, a TCanvas is created to show it. If I close the TCanvas and I ask to replot the TH1, nothing happens (none TCanvas is recreated). You can reproduce that with the following lines root -l $ROOTSYS/tutorials/hsimple.root hpx->Draw() The spectum is displayed Now, close the TCanvas and type “hpx->Draw()” again Nothing is drawn anymore

Especially to the phrase:
But note that the TCanvas is not destroyed by the GUI anymore (since the GUI doesn’t own the TCanvas). to delete it, you have to explicitly call the destructor (delete)

Anymore means: As of version 6.10.

Cheers
Otto
