One way to approach this might be to a run function (perhaps initiated by a
button click event) that sets a boolean var: bTabEnabled = false; then set
a var (statTabIndex) equal to the tabNav.selectedIndex.
The tabNavigator has a change event that will fire when the user interacts
with a tab. If the boolean is false, the tabNav.selectedIndex will be set
to 'statTabIndex'.
<mx:Script>
var bTabEnabled = true;
var statTabIndex;
function doChange(e)
{
if(!bTabEnabled)
{
tbNav1.selectedIndex = statTabIndex;
}
}
function setTabNavEnabled()
{
if(bTabEnabled)
{
bTabEnabled = false;
btn1.label = "enable tab change";
statTabIndex = tbNav1.selectedIndex;
}
else
{
bTabEnabled = true;
btn1.label = "disable tab change";
}
}
</mx:Script>
<mx:TabNavigator id="tbNav1" change="doChange(event)">
<mx:HBox height="400" width="400" backgroundColor="#003399"/>
<mx:HBox height="400" width="400" backgroundColor="#00CC99"/>
<mx:HBox height="400" width="400" backgroundColor="#993300"/>
<mx:HBox height="400" width="400" backgroundColor="#FF6666"/>
<mx:HBox height="400" width="400" backgroundColor="#00CC66"/>
</mx:TabNavigator>
<mx:Button id="btn1" label="disable tab change"
click="setTabNavEnabled()"/>
