Morphic menus

by Matthieu Lacaton

Hello everyone, I had to understand how menus work in Morphic lately and I noticed some things : 1) When a menu has strictly more than 1 submenu active it cannot regain the focus if the mouse doesn't pass over the submenus first. It is a bit hard for me to explain so I will give you an example : Open a Nautilus browser on any package and right click on a class. Now browse "Refactoring => Code Rewriting => Rewrite Code but don't click on any of these items. You will have 3 menus. Now if you exit the last menu without returning to the previous one (make a loop from the right for example if you have enough place) and go back directly to the first one you'll see that it doesn't respond (it is like frozen). I don't know if it is a bug or if it is intended but I find it strange as it is not how it is working on Windows nor Ubuntu for example. So if it is indeed a bug, what I propose as a "fix" would be this: Replace *:* > > *MenuItemMorph >>* *activateOwner Menu: evt* > "Activate our owner menu; e.g., pass control to it" > owner ifNil:[^false]. "not applicable" > (owner fullContainsPoint: evt position) ifFalse:[^false]. > owner activate: evt. > ^true > by: *MenuItemMorph >>* *activateOwner Menu: evt* > > > * | popUpOwner |* > > * owner ifNil: [^false].* > > * (owner fullContainsPoint: evt position) ifTrue: [* > > * owner activate: evt.* > > > > * ^true. ].* > > * popUpOwner := owner popUpOwner.* > > * [ popUpOwner ] whileNotNil: [* > > * (popUpOwner owner fullContainsPoint: evt position) ifTrue: [* > > * popUpOwner owner activate: evt.* > > > * ^true. ]* > > * ifFalse: [* > > > > * popUpOwner := popUpOwner owner popUpOwner. ]. ].* > > * ^false.* > It should work with any number of submenus but i couldn't find anywhere in Pharo with more than 3 menus so i couldn't test it further. 2) When you leave a submenu and quickly come back to its popUpOwner, the item in the submenu won't be deselected. So if you navigate a bit in the menu and then want to come back to this submenu, you won't be able to select the item by passing your mouse over it. It is not a big deal in 99.9% of the time as you will still be able to click on it but when this item is supposed to open a submenu it won't. You need to go to another item in the submenu and to come back. I noticed that it happened because if you are leaving the submenu too quickly there is no "mouseLeave" event generated so the itemMenu is not deselected. Thus, as it is considered as selected, if you come back to it later a "mouseEnter" event will not trigger anything. It is quite easy to reproduce with the same menu than for the 1) : Right click on a class in a Nautilus browser then browse Refactoring => Code Rewriting. Now if you quickly come back to Refactoring sometimes you'll see that Code Rewriting won't be deselected (it will still be blue after the 500ms time out). If it is the case you can go back on "Rename..." and then if you quickly come back to Refactoring => Code Rewriting, you won't be able to get the 3rd submenu. I can reproduce this very easily but it is not really a problem because it only happens if you are fast with your mouse. I did not try to fix it but I guess that reinitializing all the itemMenus to unselected when poping a menu could do the trick. 3) This one is mostly insignificant because it is quite hard to reproduce and doesn't trigger often at all. But sometimes when you quickly navigate between 3 menus (I have not been able to reproduce it with only 2 menus) when you want to go back to the first one it freezes and it doesn't handle the mouseOver events anymore (you can still click though). This is not the same thing than the first point because here you correctly pass through the previous submenus to go to the first one. I don't really know why this happens sometimes but I think it may be because the focus was not passed quickly enough between windows and one on the submenus gets deactivated and removed from the world wheras it still had the focus on him. Anyway these 3 things are not really important but I just wanted to share what i found with you in case you think it is valid. Cheers, Matthieu
