Catch information messages before they appear

[marus_b]

Hello everyone,

Is there a possibility of catching and disabling messages such as the one below? Is there any event that I could register, and if so at what level?

catching and disabling

not obvious :
STR_PROTECTIONERR
…
ApplyAttributes()
…
ErrorMessage()

I am pretty sure that such possibility does not exist. A workaround is to install a Top window listener, which automatically closes this message when it pops up. But the user would always see a flicker…

Thus, essentially, this is hard coded without any option available to have it disabled. Unfortunately, as much as I wish that would not be the case, way above my abilities and comprehension. There is no way I’d even make an attempt to alter the original code.

What @ms777 is proposing looks definitely more straight forward. Although, when you say ‘top window listener’ are you referring to one of the Calc listeners or spreadsheet?

Thank you both for your offered assistance.

Hi,
the below python code installs a TopWindowListener, which checks title and message text of all newly opened windows.
If they match (title: “Information”, message: “Protected cells can not be modified.”) the OK-button is pressed through its AccessibleContext.
There are some caveats:
It goes for title and message, so it is UI language dependent.
AFAIK the code cannot be replicated in LO Basic. One needs to press the OK button in a separate thread with a (very small) delay, which is impossible in Basic. Pressing the OK button directly in windowOpened leaves some orphaned window elements. Maybe this is a LO bug.

Good luck,
