RECT Type

Im making a small little sprite library and Im using GetClientRect to get the client area of the window so I can stretch the background image to fit to it and I cant figure out what the RECT.x1's and RECT.y1's and such, Ive tried a lot of stuffs and cant figure it out =-\.

Look in winbase.bi:

Code: Select all

Type RECT
  nLeft   As Integer
  nTop 	  As Integer
  nRight  As Integer
  nBottom As Integer
End Type

Oh, I thought winbase.bi was already compiled.

Not sure what you mean by "compiled"; here's an example of using a RECT:

Code: Select all

#include "win/winbase.bi"

Dim my_rect as RECT

my_rect.nLeft = 5
my_rect.nTop = 10
my_rect.nRight = 20
my_rect.nBottom = 30

All structures are defined in the "headers" of the library. For FreeBASIC, these are the .bi files in \inc, or for the Windows API, \inc\win. Otherwise, your program couldn't use them. To the libraries, structures in memory are just a bunch of bytes: "RECT", and it's properties are nowhere to be found in the DLL files.

You don't need to worry about including winbase.bi (the other headers, such as kernel32.bi take care of this). But that's how the win-api headers defines one. Just check the header files if you need to know what's in any other structures.

@Kcproductionz

Windows help file states that RECT is defined as:

Code: Select all

Type RECT
  Left   As Integer
  Top    As Integer
  Right  As Integer
  Bottom As Integer
End Type

but in freebasic's winbase.bi it's declared as:

Code: Select all

Type RECT
  nLeft   As Integer
  nTop    As Integer
  nRight  As Integer
  nBottom As Integer
End Type

So if something doesn't work as aspected, you have to look into the *.bi files and write your code as it's declared in the *.bi include files.

I wonder if it's possible to get the Windows CHM and replace the syntax-boxes with those from FreeBASIC's .bi files. It would be a chore - it would require a parser to get the right code examples, but it would definately be a big help.
