Change Treeview bitmap at runtime

Change Treeview bitmap at runtime

Postby Maurilio Viana » Fri Sep 15, 2006 2:19 pm

Hi!

I'm trying to implement a control access menu based in SysTreeView32.
I want to check/uncheck menu items that the user can or not access.

Code: Select all  Expand view
{-}--Menu 1
|     |---[ ] Menu 1.1
|     |---[x] Menu 1.2
|     +---[ ] Menu 1.3
|
{-}--Menu 2
       |---[x] Menu 2.1
       +---[x] Menu 2.2


Using TreeView I did any like this and I will use a bitmap to checked and other to unchecked state.

1. How can I change bitmap when we click over?
2. How can I know if a item is checked or not to save the results in a database?

Best regards,
Maurilio[/img]

Although not as fancy, a browse would be much easier to program.

Try to change the image in the oImageList and then use SetImageList() method.

Store the info in an array or a database and toggle it when you click on a tree item.

Maurilio

From the oImageList


IF oItem:nImage = 1
oItem:Set( ,2)
oItem:nImage := 2
ELSE
oItem:Set( ,1)
oItem:nImage := 1
ENDIF

Olá Maurilio,

Se eu não estou enganado eu peguei este exemplo aqui mesmo :lol:

http://geocities.yahoo.com.br/qiinformatica2000/tree.zip

Este exemplo tem vários recursos:

- Mudar a cor do fundo
- Mudar o label das opções ( Basta clicar duas vezes emcima delas)
- Opção para acionar um calendário
- Mudar o bitmap ao clicar duas vezes, etc...

Espero que te ajude :wink:

Abraços,

Rossine.
