Re: toggle button in TreeView not editable - appended with append_column_editable

["Milosz Derezynski" <internalerror gmail com>]

The togglebutton is just an indicator (going with MVC stuff here); that means that you need to set up a callback on:

http://gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1CellRendererToggle.html#0332ce9231ca8d0694f7f1e1b2350bf4

and in that callback, which gives you a string tree path, do whatever should be done when it's clicked, and change the state of the togglebutton (just negating the state of model_columns.active for that row, and using property_active() of the Renderer to reflect the new state).

Hi,

I am more or less using the TreeView example from the gtkmm book:
Figure 8.5. TreeView - Editable Cells

For some reason my toggle button in the Treeview is not editable (it doesn't
check when I click on it, but it is not greyed out). The string (userid in
the code below) actually is editable.

Is there anything special that I need to do to get an editable toggle button
in the treeview other than adding it with append_column_editable?


class ModelColumns : public TreeModel::ColumnRecord
...
TreeModelColumn<bool> active;
TreeModelColumn<Glib::ustring> userid;
...

ModelColumns model_colums;

...
sub1_treeview1->append_column_editable("Active", model_colums.active);
sub1_treeview1->append_column_editable("User ID", model_colums.userid);


many thanks

Chris
