gtkmm | TreeView | Ver: 2.8.x
Summary: Gtk::TreeModel does not offer an erase-method
Product: gtkmm
Version: 2.8.x
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: enhancement
Priority: Normal
Component: TreeView
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
GNOME version: Unversioned Enhancement
GNOME milestone: Unspecified
I developed a file-tree view (derived from Gtk::TreeView), which shows an=
icon
(acc. to the file-type) besides the name of the file (analogue to the
Gtk::FileChooserDialog/Widget). This widget is designed to support both t=
ree-
and list-stores.
Right-clicking on it shows a pop-up menu offering some functionality. One=
of
them is to erase the file. And there's the problem.
The only way I found to delete a line is via the models erase()-method. T=
hey
work fine, but you need to know the type of the model (Gtk::ListStore,
Gtk::TreeStore, ...), which the widget does not. It can call get_model(),=
but
gets a Gtk::TreeModel, which does not offer an erase().
Maybe I overlooked something, but if not the only "solution" is to dynami=
cally
check for the used model, cast to it and call erase. Of course, that make=
s the
code ugly, clumsy and error-prone.
The only clean solution I can think of is a
virtual iterator erase (const iterator& iter);
in Gtk::TreeModel (though this breaks probably the ABI)
