Working with the underlying array

Hi,
first of all congrats on a very nice product. Could you give an example on how to build a tree from the array? I would like to create it from scratch, fetching data from a database. A Demo tree could look like this
Code: Select all
root1
-test1
--test1a
--test1b
-test2
--test2a
root2
-test3
--test3a
---test3a1
How would the array need to look like and what would I need to do to construct the nodes?
Thanks,
Malte

Hi Malte, I'm not Steve but to make such a tree by scipt you could do something like this:
Code: Select all
on mouseUp
local tNodeDataArray
set the dt_general["root nodes"] of group "datatree" to "R1,R2"
put "root1" into tNodeDataArray["R1"]["label"]
put true into tNodeDataArray["R1"]["expand"]
put "T1,T2" into tNodeDataArray["R1"]["owns"]
put "test1" into tNodeDataArray["T1"]["label"]
put true into tNodeDataArray["T1"]["expand"]
put "T1A,T1B" into tNodeDataArray["T1"]["owns"]
put "test1" into tNodeDataArray["T1"]["label"]
put true into tNodeDataArray["T1"]["expand"]
put "T1A,T1B" into tNodeDataArray["T1"]["owns"]
put "test1a" into tNodeDataArray["T1A"]["label"]
put "test1b" into tNodeDataArray["T1B"]["label"]
put "test2" into tNodeDataArray["T2"]["label"]
put true into tNodeDataArray["T2"]["expand"]
put "T2A" into tNodeDataArray["T2"]["owns"]
put "test2a" into tNodeDataArray["T2A"]["label"]
put "root2" into tNodeDataArray["R2"]["label"]
put true into tNodeDataArray["R2"]["expand"]
put "T3" into tNodeDataArray["R2"]["owns"]
put "test3" into tNodeDataArray["T3"]["label"]
put true into tNodeDataArray["T3"]["expand"]
put "T3A" into tNodeDataArray["T3"]["owns"]
put "test3a" into tNodeDataArray["T3A"]["label"]
put true into tNodeDataArray["T3"]["expand"]
put "T3A1" into tNodeDataArray["T3"]["owns"]
put "test3a1" into tNodeDataArray["T3A1"]["label"]
set the dt_general["node data"] of group "datatree" to tNodeDataArray
set the dt_general["active node ID"] of group "datatree" to "R1"
lock screen
dt_paint (id of group "datatree")
unlock screen
end mouseUp
Of course when reading from a database you woud just loop these commands to fill the array. Hope this helps.

Hi Malte, hi Ismo!
First up, thanks Malte for the kind words and thanks also to Ismo for answering Malte's question for me!
The only thing I could add is that you'd also use the same approach to fill out the other properties of the nodes, such as icons etc.
For example, adding the line:
Code: Select all
put "1144" into tNodeDataArray["R1"]["icon"]
would use an image with an id of 1144 as the icon of the first root node.
Any more questions then post away!
Cheers,
Steve

Is there a list of all properties you can set? THough I love your demo stacks, sometimes a list that I just could print out might be handy.
Cheers,
Malte

Nice idea about the printable list... think I'll conjure that one up sometime soon. Another for all the commands, functions and messages should also be handy.
There's a section in the Manual called 'Node Properties', which contains a page per property.
I'll list them here with a few comments for reference, default values in brackets:
label
icon - the id of an image to be used as the node's icon
owns - a comma separated list of other node ids to be the children of this node (empty)
expand - true/false/empty although bear in mind that a root node will always display children when 'expand' is empty (empty)
command - contents of this node are passed when events are fired, to help you determine the kind of node interacted with (empty)
root style - root nodes with this property are given a special look, Mac OS X only (false)
indent - the number entered overrides the automatic indentation (empty)
accepts highlight - true/false when false, node does not highlight when clicked on (true)
direct click - true/false when true, node highlights on mouseDown... note no nodeUp message is sent (false)
