Hmm, indeed, bubble window sits a bit between both. As for a), some aspects of the behavior defined in the whiteboard benefit from not having active grabs (especially the "selection is manipulable when popup is shown" bit), and otoh I think Wayland can't separate popup/grab behaviors. Making it more similar to b) sounds worthwhile. > > I'm not really convinced of some of the choices made in the > GtkSelectionWindow class: > a) a toolbar may not be the right container for what the designers > had in mind - there was some talk of scrolling Right, on earlier stages I also found myself wondering what could fit best here, the options seem to be: * Adding scrolling capabilities to toolbars * Making an entirely different widget Given the requirement for scrolling is somewhat artificial (popup would never be as wide as the screen) and that cramming enough items there is a symptom of usability disaster, the second option seemed too far stretched for the case. Probably an useless observation in the end, but I see similarities between GtkPathBar scrolling and how it should look/work here. > b) doesn't seem necessary to use a ui manager and actions here, > since you are not even allowing addition of actions > c) adding a public getter for the toolbar will make it impossible > for us to change the implementation strategy later I made it this way so this is parallel to ::populate-menu, from all possible compromises might have been the worst decision. As you mention below, GMenuModel seems the hip way to go, but those don't map to toolbars (Is there any rationale here? I seem to have missed this), the third option is exposing UIManager bits to allow merging, but I'm unsure about its life expectancy with GMenuModel in place. > d) I'm not convinced the special-casing of cut/copy/paste is really > worth it - I would just have added these action in > GtkEntry/GtkTextView > I recommend dropping this widget altogether for now, and just > construct the toolbar with the default actions directly in > GtkEntry/GtkTextView. I'm not against that, it struck me as slightly useful to have a default ordering/toolbar style for those, it could also be made private for those to use. > > In GtkEntry, I think the use of g_timeout_add_seconds for popping up > the selection is inappropriate - you don't want the delay to fluctuate > depending on whether you touch early or late in the second.

Of course menumodel and > toolbar is not a perfect fit, either. And that last thing is the source of all dilemmas :) Carlos _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-devel-list
