How Miserable are Tree Controls?

[MoGrace]

I worked up this example for testing - try it in the IW, works great:

dim images as c
dim list as c
dim vList as c
images = <<%str%
$$mini.folder
$$mini.file.open
$$generic.preview
%str%
list = <<%str%
1+2cat1.3{DATA=Report to Preview}A
1+2cat1.3B
1+2cat1.3C 
1+2cat1.3{DATA=Report to Preview}D
1+2cat2.3E
1+2cat2.3F
1+2cat2.3G
1+2cat2.3H
%str%
result=ui_dlg_box("Simple Tree",<<%dlg%
[%I=@images%.30,15vlist^<list] |<OK>;
{ysize=1}
[.30vlist]
%dlg% )

Then using a table of reports, I tried to make an XD tree, adding fields to hold the image numbers I need.
In the IW my tree data looks correct:

auto_list_vtree = table.external_record_content_get("replist","lvl1+alltrim(group)+\".\"+alltrim(lvl2)+\"{data=\"+alltrim(dictname)+\"}\"+display","group+display")

?auto_list_vtree
= 1+2ACT_MENU.3{data=Act Menu Rep@c:\a5v11\skkv11\act_menu.ddd}Act Menu Rep
1+2A_HELP.3{data=Prn Help@c:\a5v11\skkv11\a_help.ddd}Prn Help
1+2A_HELP.3{data=Quick Prn Help@c:\a5v11\skkv11\a_help.ddd}Quick Prn Help
1+2B_MSGREP.3{data=Msg Code Matrix@c:\a5v11\skkv11\b_msgrep.ddd}Msg Code Matrix
1+2DIRECTORY.3{data=Dir Phone List@c:\a5v11\skkv11\directory.ddd}Dir Phone List
1+2INVOICE.3{data=Invoice@c:\a5v11\skkv11\invoice.set}Invoice
1+2INVOICE.3{data=Quick Invoice@c:\a5v11\skkv11\invoice.set}Quick Invoice

Here is the script:

dim images as c
DIM vtree as C

images = <<%str%
$$mini.folder
$$folder.open
$$generic.preview
%str%
dim auto_list_vtree as c
auto_list_vtree = table.external_record_content_get("replist","lvl1+alltrim(group)+\".\"+alltrim(lvl2)+\"{data=\"+alltrim(dictname)+\"}\"+display","group+display")
'msgbox("",auto_list_vtree,0)
'end
temp_count = w_count(auto_list_vtree,crlf())
DELETE a_vtree
DIM a_vtree[temp_count] as c
a_vtree.initialize(auto_list_vtree)
ok_button_label = "&OK"
cancel_button_label = "&Cancel"
varC_result = ui_dlg_box("Alpha Five",<<%dlg%
{region}
Type prompt here:;
[%D=".";I=@images%.40,25vtree^<a_vtree];
[.40vtree];
{endregion};
{line=1,0};
{region}
<*15=ok_button_label!OK> <15=cancel_button_label!CANCEL>
{endregion};
%dlg%)

But when running this simple tree control script, this is what I get:

The tree should be displaying just the DISPLAY name and the text box below the actual path to the report.

I spent most of the day on this freaking script to display in an embedded XD on a form - my error is using "." for the D directive, since the text also has a "."; so I tried "^" instead - and of course now it works fine!

Re: How Miserable are Tree Controls?

Hi Robin,

The problem is the "." contained in your DATA section. More specifically the period in your filename preceding the file extension. The tree control is reading this as a delimiter for the tree data. You can change the delimiter used in the control setup in the xdialog code. Pick a character that you won't need in menu data and then make sure you never use it. In one tree i developed based on user entered data I created data entry rules to keep it out of the data and also a routine to check the data on the way into the tree and remove that character if it snuck past.

[%D=".";I=@images%.40,25vtree^<a_vtree];

EDIT: Too slow. I was responding while having lunch. Glad you got it. Been there done that.

Hi Tim,
Glad you're here. I was looking at a new release of Fishbowl Inventory (a Quickbooks product), and really like the web style components they are using.

Especially interesting was a Tree Control of grouped reports that when one is selected, displays in a preview window. I think the use of 2 supercontrols on a form could achieve this same functionality. I have the script that populates a table for the tree control, and am now working on passing the full report path to the Report preview supercontrol.

One other thing they are doing at Fishbowl is saving filters for their reports to a table, and also use a popup form for the record selection.

This project is going to be a major undertaking to get it to work in a similar fashion - but definitely doable for the desktop.

Wow Robin.. What you have so far looks great. I can see I am going to have to pick your brain on this.

Hi Preston - you do know the FB png is only an example...I wish it were mine!

I've gotten sidetracked with my runtime issues - but will get back to this project when I have more time - stay tuned!

I was talking about the "What I have so far: report_menu.png".

Is that not yours?

Why yes, yes it is!
