Disabling the handing of drag (zoom) events in TAxis

[bmahf]

Hi all, I am working with an application project (Windows using ROOT 5.28_00b) that has a histogram with axes. The axes are able to be grabbed and dragged for zooming. I have been asked to turn off this feature, but I don’t see an option for doing so. Before I go and inherit from TAxis only in order to turn this feature off, I was hoping someone would confirm for me whether there is a way to do this without inheriting. And if not, if I were to update to the latest ROOT version (6.24) would there be enhancements that would allow me to do this? I have taken a look into the source and haven’t seen any sign of a way to do this.

You could try with:
canvas->SetEditable(kFALSE);

which disables everything and makes the canvas fixed. If you want more specific control, take a look at the first link below, with statements like:

  mypad->GetFrame()->SetBit(TBox::kCannotMove);

Disable zooming axis

Dear all, Does any one know how to disable zooming axis by pressing the left button of the mouse on the minimum point and releasing it at the maximum point? I know this is very cool, but I want user to zoom axis only by clicking zoom in button in my GUI program. Thank you very much in advance! Cheers

TCanvas::SetEditable and zoom

Hello, how is possible to use SetEditable unchecked (= false, for my users, because they don’t want to move the objects into the canvas when zooming or changing colors) but use the zoom for the TGraph and histograms? Thank you very much Best regards Andrea Bulgarelli

canvas->SetEditable(kFALSE);

is the right way. If the flag is false the method doing the axis editing immediately exits.
