The description of jDrawingView bug.
Create new Android GUI project and add jDrawingView and jButton with
the following program code.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jButton1Click(Sender:
TObject);begin jDrawingView1.Visible := not jDrawingView1.Visible;end;
Then click jButton1 multiple times – with every click DrawingView1
switches between being visible and invisible.
When jDrawingView1 becomes visible, the “status bar” hides.
When jDrawingView1 becomes invisible, the “status bar” becomes
visible.
This is a bug of jDrawingView. The visibility of jDrawingView should
not change visibility of “status bar”.

Yes!

But, now I can see how you configured this parameters...

Quote    PosRelativeToParent = [rpTop]
    LayoutParamWidth = lpMatchParent
    LayoutParamHeight = lpHalfOfParent

A simple solution:

Go to LAMW folder   "..............\android_wizard\smartdesigner\java"
,   open  the

file "jDrawingView.java" and comment the line 102 (?):

       
//this.setSys]"]>BlockediVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);


[I will improve the code, so this can be optional......]


Thank you!
