I can't see a problem with items at large coordinates, they still show tooltips in my test:
fcx.SetDocSize 0, 0, 100000, 100000
Dim t1 As table
Dim t2 As table
Dim a As arrow
Set t1 = fcx.CreateTable(99700, 99900, 30, 30)
t1.ToolTip = "test1"
Set t2 = fcx.CreateTable(99900, 99950, 30, 30)
t2.ToolTip = "test2"
Set a = fcx.CreateRelation(t1, 0, t2, 0)
a.ToolTip = "test3"
fcx.ShowToolTips = True
Please attach a file where tooltips don't work for you.
Quote:I made my own tooltip box. However, interestingly, in some very very large flowcharts (I've got one that's 65,000 units wide and has 370 nodes), GetArrowAt( x, y ) doesn't seem to work. Neither does GetTableAt( x, y ).
Check if you aren't storing mouse position in signed short integer variables, they will stop working for values larger than 32K.
