MenuItem.visible=false

Targets Windows
1

On the main menu I have FILE -> Recent Files -> menuDB(10) where menuDB is a “control array” of 10 menu place holders

Under the EnableMenuItems I have code like this

x=ubound(MRU_DB_FILES) // array of 0 to x FolderItems, only care about 1st 10 or less
For i=0 To 9
If i<=x Then 
menuDB(i).Visible=True
menuDB(i).Text=MRU_DB_Files(i).folderPath.DisplayName
Else
menuDB(i).Visible=False
menuDB(i).Text="?X" // added as a test
End If
Next i

This code works PERFECTLY on macOS, but under windows, while the VISIBLE line executes, the menu item STAYS visible

Is this a bug in Xojo? an issue with Windows? is there a workaround?

EDIT> I see this is “NOT SUPPORTED BY WINDOWS” … any ideas on a workaround?

MenuItem.Visible:

This property is only available on macOS and Linux platforms.

The list is dynamic… so it may go from 9 items to 5 items during program execution… so I cannot prepopluate the menu

4

Start with menuDB(0) only. Then add menuitems dynamically. When you need to rebuild the menu, remove all but menuDB(0) and start again.

5

where one or two items need to be hidden, I sometimes change the text to “-” and it becomes a separator

6

The only problem is you need to manually keep track of the number of items that exists. since their is no UBOUND

7

Wouldn’t that be Ubound(MRU_DB_FILES)?

“remove all but menuDB(0)”. There is no way to know how many more there are… I can’t use MRU_DB_FILE.UBOUND because it may or may not have had items removed. The issue is when the number of items in MRU_DB_FILE does not match the number of items in menuDB. Either items need to be appended to menuDB (not an issue)… .Or some unknown number need to be removed.

MRU_DB_FILE could lose items during the course of the program running (ie. the user decides to delete one or more files)
