So, I tried it, but without success. My program runs without errors, but there isn't anyting in the ComboBox. I tried so:

... megjegyzese = GTK2.ComboBox(); megjegyzese->set_model(modell()); megjegyzese->set_active(0); ... GTK2.TreeModel modell() { GTK2.TreeStore store; GTK2.TreeIter iter;

iter = GTK2.TreeIter();

store = GTK2.TreeStore(({"int", "int"})); // az oszlopok típusa iter = store->append(); store->set_row(iter, ({1, 2}));

return store; } ...

I can't find out what can be the problem...

hi!

How can i create a combo box which can contain widgets?

Cheers: Tamás

Here is a test program that works, you can try it out:

#!/usr/bin/env pike

void fixed_toggled(object w, array data, object ts) { GTK2.TreePath path=GTK2.TreePath(data[0]); // write("path==%O\n",path); GTK2.TreeIter iter=ts->get_iter(path); int val=ts->get_value(iter,3); // write("val==%d\n",val); val=!val; ts->set_value(iter,3,val); }

int main(int argc, array argv) { GTK2.setup_gtk(); object w=GTK2.Window(GTK2.WINDOW_TOPLEVEL); object vb=GTK2.Vbox(0,8)->set_border_width(8); w->add(vb); vb->pack_start(GTK2.Label("Jonathan's Holiday Card Planning Sheet"),0,0,0); object sw=GTK2.ScrolledWindow(); sw->set_shadow_type(GTK2.SHADOW_ETCHED_IN) ->set_policy(GTK2.POLICY_AUTOMATIC,GTK2.POLICY_AUTOMATIC); vb->pack_start(sw,1,1,0);

GTK2.TreeStore ts=GTK2.TreeStore(({ "string","int","int","boolean","string" }) ); object iter=ts->append(); ts->set_row(iter,({ "foo",1,2,0,GTK2.STOCK_OPEN }) ); iter=ts->append(); ts->set_row(iter,({ "bar",3,47,1,GTK2.STOCK_CLOSE }) ); iter=ts->append(); ts->set_row(iter,({ "baz",124,97,0,GTK2.STOCK_DELETE }) ); GTK2.TreeView tree=GTK2.TreeView(ts); GTK2.CellRenderer gcr=GTK2.CellRendererText(); array(GTK2.TreeViewColumn) cols; cols=allocate(5); // write("gcr==%O\n",gcr); // write("family==%s\n",gcr->get_property("family")); /* cols[0]=GTK2.TreeViewColumn()->set_title("Name") ->pack_start(gcr,1) ->add_attribute(gcr,"text",0); */ cols[0]=GTK2.TreeViewColumn("Name",gcr,"text",0); gcr=GTK2.CellRendererText(); cols[1]=GTK2.TreeViewColumn("Val 1",gcr,"text",1); gcr=GTK2.CellRendererText(); cols[2]=GTK2.TreeViewColumn("Val 2",gcr,"text",2); gcr=GTK2.CellRendererToggle(); cols[3]=GTK2.TreeViewColumn("Active?",gcr,"active",3); gcr->signal_connect("toggled",fixed_toggled,ts); gcr=GTK2.CellRendererPixbuf(); cols[4]=GTK2.TreeViewColumn("Pic",gcr,"stock-id",4); tree->append_column(cols[0]) ->append_column(cols[1]) ->append_column(cols[2]) ->append_column(cols[3]) ->append_column(cols[4]); vb->add(tree); w->signal_connect("destroy",lambda() { exit(0); },0); w->show_all();

object path=GTK2.TreePath("1"); tree->set_cursor(path,cols[1],0); return -1; }

Thank you, it's very useful. And runs without problem, it creates the tree. But I even couldn't create a similar ComboBox. :(

I think based on your example that I should render the rows with a cellrenderer, but I don't know how or where...

---

#!/usr/bin/env pike

void get_text(GTK2.ComboBox w, mixed data) { // string text=w->get_active_text(); int index=w->get_active();

// write("You chose: %s\n",text); object tm=w->get_property("model"); // write("tm==%O\n",tm); object iter=tm->get_iter(GTK2.TreePath((string)index)); mixed val=tm->get_value(iter,0); write("val==%O\n",val); }

int main(int argc, array argv) { GTK2.setup_gtk(); object w=GTK2.Window(GTK2.WINDOW_TOPLEVEL); // GTK2.ListStore ls=GTK2.ListStore(({ "string" })); object cb=GTK2.ComboBox("string"); cb->append_text("test 1"); cb->append_text("foo"); cb->append_text("fred"); cb->append_text("scooby"); w->add(cb); w->show_all(); cb->signal_connect("changed",get_text,0); w->signal_connect("destroy",lambda(){ exit(0); },0); return -1; }

Just modify it to add specific cell renderers as per the previous example.
