THE SITUATION

-------------------------------------

I am creating text labels

h = text([.5 1],[.5 .5],{'hi','hello'});
plotedit on

which individually have a contextmenu that allow to change their text properties, e.g. try to right-click and change Font...

However, I'd like to keep the same contextmenu for a hggroup() of text() objects.

hg = hggroup;
set(h,'Parent',hg)

The text properties are not reachable from the context menu associated to hggroup().

-------------------------------------

THE QUESTION

-------------------------------------

Is there a way to have a contextmenu for the hggroup object with the menus for the text properties without recreating it manually with all the callbacks? For instance, scatter() creates such a contextmenu

figure
load seamount
scatter(x,y,5)
plotedit on

you can right click and change some properties of all children of the hggroup.

I have the feeling the solution already exists but it's undocumented and well hidden.

I've been looking into $MATLABROOT\toolbox\matlab\specgraph, graph2d, graphics to no avail.

I suspect that the various schemas might play a role, i.e. what if I define a schema for text()?

PS. Let me know if I didn't express myself clearly.

I quickly tested it and I like so far the behavior. I will play with it a bit longer to see if the solution satisfies my objectives (which are still not completely determined).

At the end I did not find a way around, and recreating the whole contextmenu takes quite some time (which is what I wanted to avoid).

Oleg, you can simply reuse the localGetNonScribeScribeContextMenu() subfunction in %matlabroot/toolbox/matlab/graph2d/private/plotSelectMode.m. It is called by localWindowButtonDownFcn() in that same file whenever you right-click an object in plot-selection mode.

Whenever you right click an object in this mode, the standard scribe context-menu (which include all the text items that you need) is recreated and added to the bottom of the object's existing context-menu (if available).

So you can simply cut all the red tape and reuse the localGetNonScribeScribeContextMenu() code directly when you create the initial context-menu.
