I don't see "Tree Control" as a valid Origin User Control type. Am I missing something, or is it not available to Origin 8 C development?
I want to be able to import a CSV with coded headers so I can build a hierarchical tree control of available data types with color coding and expandable branches and then be able to select data to chart.
Origin Ver. and Service Release (Select Help-->About Origin): 8.1
Operating System: XP |

TreeNode is right, maybe you can try using GetNBox to see if that will be good enough.
This link will give you some immediate simple examples:
http://ocwiki.originlab.com/index.php?title=OriginC:GetNBox_%28global_function%29
This link points to the main page that cover various detailed topics in using GetNBox.
http://ocwiki.originlab.com/index.php?title=Category:GetN_Dialog
It is also possible to use DynaControl in your custom dialog and it also accepts the same tree as used in GetNBox, so there is basically little of no programming needed except to construct that tree.

Ok,
now I think I have a better understanding of what you want.
Let me have another try... ;D
You want to create a user-Interface, where a Tree holds the entered data?
For example a User Interface with Checkboxes, Lists, drop-down menues?
When thats your intention, there is a Implementation in Origin:
called GetNBox. In fact its a collection of Makros.
With these Makros you can set up a User-interface where all the
elements you need, checkboxes, lists and so on...will be put one after another.
All the values, you enter, or the state of a checkbox, holds a Tree.
You can access this tree, save these values, execute functions, depending on
these values.
There is also a Event-Handler function, which is executed, when user changes
values in the dialog.
I have experience with that, because I use these Makros as a possibility for
user-Interface intensivly, and it works fine.
But if I got you wrong another time, perhabs you must ask somebody else ;D
Then I am not able to understand your problem ;D

TreeNode, thanks for the response. I was trying to get at how to visually represent in a user interface a selectable tree node. In windows programming there is a user interface element called a Tree Control that does not appear to have been implemented in Origin 8 yet.
I was able to get a DynaControl working that appears to function like a Tree Control, but I don't see any samples, and the documentation is thin. Looking at the comments in the code it looks like this weas being worked on as of late 2009.
I think I will just use two side-by-side listboxes and implement my own tree-like userinterface element.
Thanks! |

Hi,
I am not really sure what you are talking about.
There are composite datatypes Tree, and TreeNode in Origin. The Reference of
the class TreeNode shows many methods, doing operations on TreeNodes, like
getting, setting Values, Attributes, find Nodes by Attribute and so on...
The Tree class supports direct Import of XML data. So perhabs, you could parse
the data from CSV-format to XML-format? After that you would just have to do the
following:
bool import_xml_data()
{
Tree tr; // declare Tree object
string strFile = "C:\\myProject\\xmlData\\myData.xml";
// import XML-data into Tree
tr.Load( strFile );
// Check, if import was successful
if(!tr)
{
out_str("Could not import xml-Data into Tree!\n");
return false;
}
out_tree(tr); // show Tree
return true;
}
But perhabs I miss understood your problem, and you are talking about
something different.
Or do you mean with "Tree-Control", that you want to set the import-properties
for your CSV-data, using a Tree that holds these settings?

Ok, so it looks like DynaControl is a form of tree control, but I can find very little docs on it and no samples. I was able to lay down a Tree Control in VS2008 and use the following code to "cast" it to a DynaControl:
DynaControl myDC;
myDC.CreateControl(GetItem(IDC_TREE3).GetSafeHwnd());
myDC.SetTree(tr, DYNALAYOUT_BACKGROUND_GRAY);
But I have no idea on how to customize it so I can make nodes/leafs selected/unselected.
Anyone have any experience with this? |
