Bug? drawing panel on tabhost and canvas

Hi all,

We may have found problems using b4a


1) If you use the ' android:targetSdkVersion="14" ' and if you set the disegner at 100%x and 100%y , the panel will not take full screen. So, if you unset the ' android:targetSdkVersion="14" ', the resizing will work correctly.

Is there a way to make it work correctly?



2) In ' Canvas ' object, if you set a panel's colour from the designer and you try to draw something like a line, the line will work correctly, instead, if you set a panel's colour from the source code, the line will not work.





Attached here you can find a little sample code to reproduce the issues

Can you try to reproduce it with TabHost without TabHostExtra? Note that you should use File - Export as zip when uploading files.

of course I've commented tabhost extras lines and problem persist when you are on landscape panel doesn't draw correctly and I can't reload layout to make it works.

There were several problems in your code:
1. If you want the panel to fill the tab then you need to set its anchors.
2. You shouldn't set the panel color after you initialize the canvas. You can use Canvas.DrawColor instead.

Check the attached project.

We'd like to use all available spaces.
Overall in landscape mode cutting even few pixels reduce a lot of space for user interface.

Using anchors (first image) the results is only for eyes, only tabbar bottom border is higher than normal.
(Seems draw correctly but panel on TAB2 has the same dimension of TAB1, but there is other pixels available!)

I see it too. Seems like the TabHost is drawn a bit differently in this case. You can manually extend the panels:

Ok Erel Thanks you, in designer when landscape I can use a variable with +7dip instead of 100%y for drawing controls using all the available space.
Thank you for your support
