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

Code: Pascal  [Select][+][-]
  1. procedure TAndroidModule1.jButton1Click(Sender: TObject);
  2. begin
  3.  jDrawingView1.Visible := not jDrawingView1.Visible;
  4. 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”.
How to fix this bug of jDrawingView?

Yes!

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

    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.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);


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


Thank you!
