Android Question What's is wrong with this Designer Script?

[incendio]

Hi all,

I have a problem with designer script for SetTopAndBottom command (Sample project Attached)

In my layout, there is pnlMain, pnlMain contains 3 panels, pnlTitle, pnlInput & pnlTbl.
pnlTbl contains 1 panel, pnlData.

On each panels, SetTopAndBottom command seem OK, but on pnlData is not OK.

Here is the sample on designer script :

pnlMain.Width = 100%x
pnlMain.Height = 100%y
pnlTitle.Width = pnlMain.Width

pnlTitle.Top = 0
pnlInput.SetLeftAndRight(4dip,pnlMain.Width-4dip)
pnlInput.SetTopAndBottom(pnlTitle.Bottom + 5dip,200dip)

pnlTbl.SetLeftAndRight(4dip,pnlMain.Width-4dip)
pnlTbl.SetTopAndBottom(pnlInput.Bottom + 5dip,pnlMain.Bottom - 5dip)

pnlData.SetLeftAndRight(8dip,pnlTbl.Width-8dip)
pnlData.SetTopAndBottom(8dip,pnlTbl.Bottom -15dip)
'pnlData.Top = 8dip
'pnlData.Height = pnlTbl.Height -15dip

The last command pnlData.SetTopAndBottom(8dip,pnlTbl.Bottom -15dip) is supposed to set pnlData bottom 15dip above pnlTbl bottom, but it was not correct.

Anybody knows what is wrong with those codes?

Thanks in advance.

pnlData is a child of pnlTbl. So its coordinates are relative to pnlTbl.
The correct code is:

pnlData.SetTopAndBottom(8dip,pnlTbl.Height -15dip) 'height instead of bottom

What about pnlTbl?

This panel is a child of pnMain, yet a command
pnlTbl.SetTopAndBottom(pnlInput.Bottom + 5dip,pnlMain.Bottom - 5dip) return a correct result.

This is also a mistake. However pnlMain.Top is 0 so you don't see it.

Ok, thanks for your explanation.

That's because PlMain has the same size as the Parent activity.
SetTopAndBottom and SetLeftAndRight set their positions relative to its parent, so if its parent has a top and bottom of 10%y,90%y its has a 80%Y height, setting one of its childs to hava a botton equal to the parent's 90%y will make it offset by 10%y
That's why it is so easy and yet so tricky to use the scripts... everything can and should be relativized... with caution
