Arrow tooltips
Jun 3rd, 2013 at 4:35pm
Print Post  
When creating my flowchart, I'm calling PutShowToolTips( TRUE ) and also, for good measure, calling PutToolTipAutoPop( 5000 ) and PutToolTipDelay( 1000 ). I'm setting tooltips on my arrows with PutToolTip( ), but I see nothing when I hover over them.

Anything I'm missing?

If there are any nodes behind these arrows, try setting HitTestPriority = ZOrder.

I hope that helps,

Definitely key -- thanks -- but not all I'm lacking apparently. Let me play around with it and see if I can figure it out.

On the subject of arrows, is there any way that one can combine bhCreateArrow with bhPanAndModify? I need to be able to move objects around and scroll the flowchart by dragging it, but I also need to be able to create arrows.

Try the following:

Code
Select All
Private Sub Form_Load()
    fcx.FireMouseMove = True
End Sub

Private Sub fcx_MouseMove(ByVal docX As Long, ByVal docY As Long)
    Dim b As box
    Set b = fcx.GetBoxAt(docX, docY)
    If b Is Nothing Then
        fcx.Behavior = bhPanAndModify
    Else
        fcx.Behavior = bhFlowChart
    End If
End Sub


I hope that helps,
Stoyan

I just cannot get tooltips to show up at all. I tried putting one on a box that was definitely the only thing at a certain position. Nothing. There must be something that needs to be done besides calling PutShowToolTips( TRUE ).

Note: I'm using Wn32 C++.

It seems a few years ago you managed to show them by enabling ShowToolTips at a later point, try that again:
http://mindfusion.eu/Forum/YaBB.pl?num=1244143856/2#2

ShowToolTips associates a Win32 tooltip control with the flowchart window, but some MFC or ATL initialization code in your application might be overriding it, so try setting ShowToolTips as late as possible.

I hope that helps,
Stoyan

Sadly, that doesn't seem to be helping with the arrow tooltips. I've tried turning them on right before setting the tooltip text and also calling ShowToolTips( FALSE ) and then ( TRUE ) even on MouseMove. But you're right that something might just be incompatible. I can easily do fake tooltips.

Do you mean they work for nodes now but not for arrows? Have you set the HitTestPriority property to ZOrder?

Yes, I set that property. Currently, they neither work for arrows nor tables.

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 ). I've made sure that all of my z indices are set correctly.

Ideally, I'd like to get your tooltips working; however, failing that, I'd like to figure out why GetTableAt and GetArrowAt are returning null.

I can't see a problem with items at large coordinates, they still show tooltips in my test:

Code
Select All
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.

Check if you aren't storing mouse position in signed short integer variables, they will stop working for values larger than 32K.

actually i'm using unsigned shorts (maxima of 65535) but that's probably still what's happening -- my width of 65,000 might really be 66,000 and it might be failing on the edge. right. that's embarrassing.
