There is now a new API in Gnoga.Gui.View
procedure Fill_Parent (View : in out View_Base_Type);
-- Cause View to expand its height and width to fill its parent's client
-- area. View's parent must have Position set to Absolute, Fixed or
-- Relative for Fill_Parent to work properly.
-- Note:
-- Position will be modified for View to either Absolute or Relative
-- if Absolute positioning fails (i.e. on IE)
Not bad that this is the first time I've had to truly write "work arounds"
for different browsers. I did have to deal with IE returning floats for
mouse locations, but that doesn't count, just needed to trunc results for
that.
I will say I did spend hours on the issue of using only CSS and/or HTML to
get this to work but I have a very clear understanding of the layout models
and sadly the quarks between browsers now.
I have tested Fill_Parent on Chrome, Opera, Firefox and IE. Opera is webkit
based (Chrome is now Blink based) so native gtk and safari should work like
Opera as well, but I haven't had a chance to test yet either.
(test/pack.adb uses Fill_Parent, a black border will appear around the
right middle panel with the button in side the panel when working).
Of course this makes the Grid_View_Type a complete replacement for the
Docker. Just create child views with the Panel of the Grid you want it to
fill and then on the child view call Fill_Parent.
I will expand test/pack.adb with a bit more, like using Layout_Float to
show packing controls and using Grid_View_Type for laying out forms.
