Dear all, how do we create an mouse click event binding for a grid? I look over the docs and cannot find any clue about it. google did not help either.

If in doubt, it can be worth searching the wxWidgets docs as a backup. Just prepend ''wx'' to the class name for searching (eg wxGrid). With any widget, you can also use the lower-level mouse event handlers, eg grid.evt_left_up alex
Hello Hendra, You should be able to monitor evt_left_down, and evt_left_up for a click event. The actual detecting of a Click, would require that in evt_left_down, you store the mouse position, and the time at which the event was generated, then on evt_left_up, take the current time, and subtract the time at which your program received evt_left_down, to see if it''s within a normal time frame to qualify it as a click, and you would want to make sure that the mouse position matched the first one, then fire off your method you want to execute when a click occurs on the grid. Take a look at the Event sample folder, for a way to do this, through a custom event handling system. hth, Mario 2009/3/30 hendra kusuma <penguinroad at gmail.com>> Dear all, > > how do we create an mouse click event binding for a grid? > I look over the docs and cannot find any clue about it. > google did not help either. > > Thank you > Regards > Hendra > > > > _______________________________________________ > wxruby-users mailing list > wxruby-users at rubyforge.org > http://rubyforge.org/mailman/listinfo/wxruby-users >-- Mario Steele http://www.trilake.net http://www.ruby-im.net http://rubyforge.org/projects/wxruby/ http://rubyforge.org/projects/wxride/ -------------- next part -------------- An HTML attachment was scrubbed...

This is what I want to do I fill datagrid with all data from a table first column is boolean, an is set with set_col_format_bool (appear as checkbox) I set all other columns to readonly so when I click the first column, it will change the value (true or false) and update the table (the primary key is at 2nd column) current state I click cell on first column, move focus to clicked-cell click the cell again, cell change to textbox, I can change the value there expected behavior click cell on first column, and it toggle the value between checked and unchecked Thanks Hendra> > > >> >> >> a >> _______________________________________________ >> wxruby-users mailing list >> wxruby-users at rubyforge.org >> http://rubyforge.org/mailman/listinfo/wxruby-users >> > >-------------- next part -------------- An HTML attachment was scrubbed...

I believe there are a couple of problems. First, you haven''t actually
passed the GridEvent to your handler. Second, it seems you only want to
call event.skip if event.get_col is 0 (I''ve never used a Grid,
I''m assuming
the cols and rows are 0-indexed); It sounds like you want normal event
processing to stop if they simply check the checkbox in the first column, ie
the cell doesn''t get highlighted afterwards, and then normal event
processing to continue on any other column. I think the code you want
should probably look more like this:
evt_grid_cell_left_click() { |e| do_click(e) } # pass GridEvent as e
def do_click(event) # get the event passed earlier
puts ''ok''
event.skip unless event.get_col == 0 # do normal processing except on 1st
col
end
Also, since evt_grid_cell_left_click doesn''t take an id parameter, it
seems
you''ll probably have to put that entire chunk of code inside of a class
declaration for the Grid itself (either extending Grid or the variable
referencing it). Otherwise wxRuby won''t know what control
you''re trying to
catch an event on. If there''s some other way around that, someone
please
correct me.
Hope this helps,
--Steve
