Left, Top, Right, Bottom

[FinalVersion]

This still mocks me, I still don't get where left, top, right and bottom are located.

I'm assuming it looks something like this.

FinalVersion,

They are the coordinate values of the corners:

x1, y1  #--------------------------# x2, y1
        #                          #
        #                          #
        #                          #
        #                          #
x1, y2  #--------------------------# x2, y2

Left   = x1
Top    = y1
Right  = x2
Bottom = y2

Still not very clear, sorry.

Finalversion,

How do you write any code if you do not understand this simple concept then?

You position a label in a GUI like this GUICtrlCreateLabel("Fred", 10, 10, 100, 50). The coordinates of the label are are as follows:

This is the GUI:
#------------------------------------------------#
|                                                |
|        This is the lbel                       |
| 10, 10 #--------------------------# 110, 10    |
|        |                          |            |
|        |                          |            |
|        |                          |            |
|        |                          |            |
| 10, 60 #--------------------------# 110, 60    |
|                                                |
|                                                |
#------------------------------------------------#

Left   = 10
Top    = 10
Right  = Left + Width = 10 + 100 = 110
Bottom = Top + Height = 10 + 50  = 60

Some functions need Left, Top, Width, Height. Others need Left, Top, Right, Bottom. Just read the Help file carefully to see which.

Your first picture is pretty much it.

[bogQ]

Let me try

[ripdad]

* = pixels

measured at column 5

0 1 2 3 4 5

1 * * * * * <- column (5), row 1 = 5,1

2 * * * * * <- column (5), row 2 = 5,2

3 * * * * * <- column (5), row 3 = 5,3

4 * * * * * <- column (5), row 4 = 5,4

5 * * * * * <- column (5), row 5 = 5,5

-edit-

well something like that -- i can't get it to display properly like in the editor

.

It is like when using an area selection tool, you start at the top left corner and go to the bottom right corner. Those are the 2 coordinates you need.

So basically, ( left, top, right, bottom,

left, top= x,y of the top-left corner of your area

right, bottom=x,y of the bottom-right corner of your area

x,y

...|--------|

...|........|

...|--------|

.............x,y
