Hey all,

Can't seem to find a way to change the color of text in a TreeViewCustomGui "tree" column. I've tried DrawCell from TreeViewFunctions, but it doesn't appear to effect anything in that column.

What I want is to color 'folders' differently than 'files' so that the difference is noticed (since there is no other way in cases where the folder has no contents).

Thanks,
Robert

Couldn't you use TreeViewFunctions::GetColors()?

Hmmm. And here I thought "GetColors" would GET the colors of something and not SET the text colors. Remind me to not only look at the method list, but to check out each entry when searching for appropriate ones.

Thanks again,
Robert

Well, not quite. Not sure what to ~do~ with this. Here's what I tried, with no effect (note: GetTreeColorXX() return GeData* ) :

  
virtual void GetColors(void *root, void *userdata, void *obj, GeData* pNormal, GeData* pSelected)  
{  
     RuntimeItem* rti = (RuntimeItem* )obj;  
     pNormal = rti->GetTreeColorNormal();  
     pSelected = rti->GetTreeColorSelected();  
}

And here's where I set up the GeData (ignore the irrelevant code) - pNormal and pSelected are GeData's as class members to mine and they are set during Construction:

  
if (type == ITEMTYPE_RUNTIME)  
{  
     pNormal = GeData(Vector(1, 0.7, 0));  
     pSelected = GeData(Vector(1, 1, 0));  
     if (rt == NULL) rt = this;  
     GetOneAhead(rt, riid);  
}  
else if (type == ITEMTYPE_FOLDER)  
{  
     pNormal = GeData(Vector(0, 0.7, 0));  
     pSelected = GeData(Vector(0, 1, 0));  
     if (rt == NULL) rt = this;  
     GetOneAhead(rt, riid);  
}  
else  
{  
     pNormal = GeData(Vector(0,0,0));  
     pSelected = GeData(Vector(1,0,0));  
}

First of all, there's a bit of naming confusion. When most people see "pNormal" they will think "pointer to normal". That's the way the prefix "p" is used in the signature for GetColors(). However, you seem to use the name "pColor" for a non-pointer GeData. And then I assume that GetTreeColorNormal() returns &pNormal?
Anyway, the main problem is when you do "pNormal = rti->GetTreeColorNormal()". This will simply assign the local copy of the pointer "pNormal". You need to do "*pNormal = ..." to set the value of the pointed GeData instead.

Nope.

In RuntimeItem, GeData is a class member

GeData pNormal;
GeData pSelected;

Okay, I kept the 'p' prefix just to keep naming conventions synonymous.

In GetColors, I retrieve these members by sending &pNormal;, &pSelected; with the functions GeData* RuntimeItem::GetTreeColorNormal(), GeData* RuntimeItem::GetTreeColorSelected().

So, GetColors is getting pointers to the GeData's. Still doesn't resolve why it doesn't work.

Sorry, I should have been more explicit:

    
    
    virtual void GetColors(void *root, void *userdata, void *obj, GeData* pNormal, GeData* pSelected)  
    {  
         RuntimeItem* rti = (RuntimeItem* )obj;  
         *pNormal = *rti->GetTreeColorNormal();  
         *pSelected = *rti->GetTreeColorSelected();  
    }

Otherwise your only assigning to the local pointer variables, not the pointed GeDatas. In other words, the outside world cannot detect that you've assigned your pointers. Or have I misunderstood where the above code is located?

So, what you are saying is don't set the pointers to pointers, but set what is pointed to by them?

*pNormal = GeData

and not

pNormal = GeData*

Will have to try that, but I think that I have already tried setting the pointer's data directly to a GeData element with no results.

Thanks,
Robert

That worked!

Maybe since my first tests used GeData's directly in the TVF:

*pNormal = GeData(Vector(r,g,b));

... I considered that it had to be a pointer-pointer assignment not realizing that the scope (and data) probably just disappeared in the first instance.
