 Posted: Tue May 08, 2007 9:53 am Post subject: [module] TVX - Tree View eXtension |
 |
|
TVX is extension for TreeView control to support moving, inserting and deleting. Once you call TVX function your tree view will become extended.
Key Bindings :
| Code: | INSERT - add new item
SHIFT INSERT - add new group
DELETE - delete item or group
SHIFT UP - move item up
SHIFT DOWN - move item down |
Current API is as follows (documentation currently in the source):
| Code: | TVX - Initialisation function. Mandatory to call before you show the TreeView.
Walk - Walk the menu and rise events. Check out Save button in Example
Move - Moves tree view item up or down
Copy - Copies menu item or group to another location. Exists in the code as TVX_CopyItem, but still not documented and properly interfaced.
|
Basic Example:
| Code: | Gui, Add, TreeView, h400 w300 vMyTree
root := TV_Add("Root", "" , "Expand")
loop, 10
P := TV_Add(A_Index, root)
TVX("MyTree", "Handler", "HasRoot CollapseOnMove ")
Gui, Show, autosize
return
Handler:
return
#include TVX.ahk
|
Check out Walk example here
Documentation
| Code: | ;----------------------------------------------------------------------------------------
; Function: TVX
; Initialisation function. Mandatory to call before you show the TreeView.
;
; Parameters:
; pTree - AHK name of the TreeView control
; pSub - Subroutine for TreeViewX, the same rules as in g.
; pOptions - String containing space delimited options for setting up TreeViewX
; pUserData - Base name of the array holding user data.
; This array is indexed using tree view item handles.
;
; Options:
; HasRoot - TreeViewX has root item - the one containing all other items.
; Root item can't be moved, edited or delited, and items can not
; be moved or created outside of it. This option need to be set
; after root is already added to the menu, as TreeViewX need to
; know the root menu handle.
;
; CollapseOnMove - When moving item out of of its container, this option makes container collapse
; EditOnInsert - Automaticaly enters edit mode upon insertion of new item
;
; Example:
;>
;> TVX("MyTree", "Handler", "HasRoot CollapseOnMove")
;>
;----------------------------------------------------------------------------------------

;
; Type Param
;
; + - Iteration start, root handle
; M - Menu item, menu handle
; I - Item, item handle

majkinetor, nice work!! 
Now I'll retry a script that I discarded exactly because these modifying possibilities were missing.
Thanks for this facility! |

This is Walk example. It will save entire tree in the text file on button click.
Walk handler is called for every item in the treeview and few more times for pseudo items (end of menu, end of iteration). Events specify some points of general interest. You can use Walk for whatever kind of processing you need upon treeview enteries, while being informed about hierarchy details.
| Code: | OnBtnClick:
TVX_Walk(root, "SaveHandler", Event, Item)
return
SaveHandler:
TV_GetText(txt, Item)
if Event = + ;start of iteration, called only for root
{
FileDelete, _out.txt
FileAppend %txt%`n, _out.txt
line := "|-"
}
if Event = E
StringTrimRight, line, line, 2 ;end of group
if Event in I,M ;I=simple item, M=group item
FileAppend %line%%txt%, _out.txt
if Event = M ;start of group
line .= "--"
if Event = - ;end of iteration
Msgbox, TVX saved in _out.txt
return

cool additions to TView control... I did similar additions from scratch in a couple of my scripts but never coaxed myself into writing a function. thanks for doing it!

Different stuff.
- Camstudio (freeware, portable)
Makes a video of what you do in region you specify. You have hotkeys to pause recording so you can pause when you want to add anotations. You also have hotkey "next anotation" so if you order then chronologicaly you can just record and press this hotkey when you want. This will generaly give you about 60MB avi.
- GIF Movie Gear (shareware, can be portable)
Then, you load this video here. It will show frames, so you can remove frames you don't like. After that you optimise gif with this tool so it becomes very small (optimisation means that only picture differences will be kept, so if you have several static frames, only 1 will be saved, if dot moved on 4th frame, only that dot will saved..). Then you save it as gif animation which gives you 300KB for longer gifs.
- Bannershop GIF Animator (shareware, can be portable)
You can create here banners , like the one in your signature. You can save short bunners and insert them at frame location using GIF Movie Gear. This allows you more proffesional presentation, with transitions etc..
For instance, take first frame of your movie and save it as a picture. Load this picture in Banner Animator and create fade in. Save this gif and load it at the start of your movie in GIF Movie Gear. This joines transitional gif and large gif into single one.
Don't create gifs larger then 300KB. Although they work nice standalone, they usualy crash all browsers or make local CPU burn. 300KB is generaly enough for 2 minutes of presentation. This depends on contenst of your presentation. If frames are "too moving" optimisation will be less effective and you will have larger gif.
