I have soem area coordinates Webiview and Panel on Activity.

I want to control "gesture2" when touch only 1 finger on webview. (Panel visible= false)
if webview"gesture2" has a2 finger ,
I change "Panel visible =true" and I want to control "gesture3"
So i cant run.
Sortly;

1 finger >> panel visible=false + gesture2 runs...
2+ finger >> panel visible=true(bringfront) + gesture3 runs...

Code std gesture multitouch example.
I littile change it.

B4X:
#Region Module Attributes
    #FullScreen: False
    #IncludeTitle: True
    #ApplicationLabel: Multitouch Example
    #VersionCode: 1
    #VersionName:
    #SupportedOrientations: unspecified
    #CanInstallToExternalStorage: False
#End Region

'Activity module
