Tab contols used in LBW

[davidcoker]

Hello Alyce,

When working with the tab control from within LBW, the comments suggest using "Hide or Show" for any controls associated with each tab:
   'Returns 0-based index of selected tab. Call this routine on a timer
   'or from another routine to see which tab is selected.
   'Hide or Show controls like buttons that are associated with current tab.

Can you point me to an example of how to structure the code for a control(s) associated with the tab control? ...I tried searching the LB forum with no luck, so I figured I'd just bug you here.

Your help will be much appreciated!

Hey Doc,

There are lots of ways you could do it, like having handles of controls in arrays, but the simplest would be a select case.

Pseudo code

[tabClicked]
gosub [hideAllControls]
'if you have a single sub that hides everything, you have less code

select case TabIndex

case 1
'statements here to show all controls associated with first tab
case 2
'statements here to show all controls associated with second tab
case n
'statements here to show all controls associated with nth tab
end select


Remember that controls which accept new strings of text, like textboxes, need a ! in front of command strings, while controls like graphicboxes don't.

#1.textbox "!show"
#1.graphicbox "show"

...to date I still haven't done a lot of coding with LB (this may change pretty quickly ), so I wasn't quite sure which way to head with it.

Thank you very kindly nice lady, much appreciated!

Boy do I feel particularly stupid. (moreso than usual)

This afternoon I started working my way through your LB4 companion guide and found not one, but three very nice samples for the tab control.

...another "doh!" moment for you know who.

It would be nice if Liberty BASIC had native access to the common controls, but it does not. Some of these are quite easy to implement by API. Some take more code and are more complicated. The tab strip is one of these, as are listviews and treeviews.

Here's a little newsletter article with some tab strip stuff in it:

LBW attempts to make the creation of these API controls as easy as possible by setting up the skeleton, but they still require some creative coding.
