Becose CBasic cant draw round rectangle directly
i try with API function but dont work
i need litlle help !!!
'how draw Round Rectangle with API function
DEF win:window
def hendle:int
Declare "gdi32",RoundRect(hdc As int, X1 As int, Y1 As int, X2 As int, Y2 As int, X3 As int, Y3 As int) As int

WINDOW win,0,0,350,350,@MINBOX|@MAXBOX|@SIZE,0,"Main-",main


retval()
'VB example
'retval = RoundRect(hdc, 25, 30, 100, 50, 10, 5) :' draw the rectangle

run = 1
waituntil run = 0
closewindow win
end

sub main
select @class
case @idclosewindow
run=0
case @IDCREATE
CenterWindow win
endselect
return

SUB retval
def hdc:int
handle = GetHDC win
RoundRect(win, 25, 30, 100, 50, 5, 5)
' draw the rectangle
return

You need to release the device context, and pass the DC NOT the window.  The API knows knothing about CBasic windows.

SUB retval
def hdc:int
handle = GetHDC win
RoundRect(handle, 25, 30, 100, 50, 5, 5)
' draw the rectangle
ReleaseHDC win, handle
return

aurelCB

wow cool,thanks GWS.!
may i ask you some?
how change frontpen without frontpen command
also with API or something else
thanks...

aurelCB

i forget becose frontpen no efect on API drawed

GWS

The text color is set for the TextBox control in the:

setcontrolcolor win,1,rgb(red,grn,blu),fill

statement ..  :)

you are not understund my question becose my enlish is bad.
i ask you how imitate FRONTPEN command with API function
if this exists
like
selectpen r g b
something like that?

Ionic Wind Support Team

See the CreatePen windows API function.  Drawing with the API isn't as straightforward as we make it in EB.   Using the API you select and deslect objects out of a windows device context.

Thanks again mr.Paul .I will tray use
API for drawing becose some integrated grafics card
dont draw simple drwing objects and not recognized
Frontpen command properly or maby becose use RAM
for memory.

Ionic Wind Support Team

Then the API wouldnt work for you either as the frontpen command calls CreatePen and SetTextColor.
