Context menu rotate3d works once !

Hello,

I'm working with MatlabR2012b and uicontrols.

I'm trying to activate a contextual menu into an axe to

• swap between rotate3d / zoom / save picture
• Axe is into a figure (that will contain uicontrols).

- For FUNCTION (here: ctx_save) and ZOOM : everything is correct

- For ROTATE3D : it works only ONCE !!!

(code is below)

Scenario : run my function context_menu_rotate_zoom

(other function ctx_save, ctx_rotate, ctx_zoom will be in seperate files)

• right button into the fig : context menu appears (Rotation/zoom/save)
• right button into the axe : context menu appears (Rotation/zoom/save)
• right button on the surface : nothing but it's ok as hittest is on

== 1/ right button and select context menu zoom : (pop up window+zoom on) : it's OK

You can zoom using left button

You can click on right button context menu to zoom and save several times.. it's OK

right button into the figure : Nothing !

QUESTION 1 >> Does "ZOOM ON" desactivate context menu for parent ?

== 2.1/ right button and select in context menu ROTATION: (pop up window+rotate on) : it's OK you can rotate the picture

== 2.2/ right button and select a second time on context menu ROTATION: (pop up window+rotate on) : it's OK

== 2.3/ right button... The rotate3d context menu appears with :reset to original view/Goto X-Z...

QUESTION 2 >> How can I overwrite Context menu for ROTATE3D the same way it works for ZOOM ?

Thank you for your help ! Alain

Hey Alain,

I know it's been a long time since you ask this question, but I'm facing the same problem now.

When I create an UIContextMenu with one menu entry for rotation, I can overwrite the standard rotation UIContextMenu. Everything looks fine, when I click on this menu - rotation mode is activated. When I right click again, I also find my UIContextMenu and can deactivate rotation again. But when I rotate an axes and I try to open my context menu again, my context menu has been reseted with the standard rotate3d context menu with :reset to original view/Goto X-Z

You also described this behaviour in your question.

Have you or anyone else found a solution for this? (I'm using Matlab 2013b)

Thanks for your help, Jan

Hello,

This is a bug in MATLAB that was fixed in R2014a. As you say, after rotating, rotate would reset some user set values before the next rotation.
