Perhaps disabling the other buttons while toggling them would help - the
disable state could be used to prevent recursion - the handler can check it
and ignore the event...?

Subject: [cvsgui-dev] problem with rf


Hello Folks,

I discoverd a problem in the rf.
Toggled UI objects (stateful) are handled the same way stateless
objects are. This results in incosistencies between the internal
state of gcvs and the state shown at the user interface.
This hits UCvsFrame.cpp if one clicks OnViewModified(). In this case
"kFilterChanged, kFilterAdded, kFilterRemoved, kFilterConflicts" are
changed. Afterwards an UpdateUI() finds the internal state of these
modied and tries to set the displayed stata at UI site respective. But
this results in a new button pressed event for OnViewConflict() and
all the others, which in turn change the state not being
"kFilterModified" any more. So we get a perfect recursion!

So what to do?

It is not possible to prevent gtk from emiting a ButtonPressedEvent
when the state of a ToggleButton is changed programaticaly. But in
uwidget::gtkclicked() I can determine the type of clicked button. And
it ist possible to get the state of the ToggleButton.
So it would be possible to define a new EV_CMD_TOGGLED and pass the
state along with this.
But that requires a lot of changes throu the whole code.
Has anybody any better solution???
