1. [WIN] richedit: how to programmatically select text?

I tried to select text in a richedit (using Win32Lib 59.1) by using
setIndex, & it wouldn't work;  is this a bug that's corrected in more recent
versions, or is there an alternate way to programmatically select text in a
richedit control?

The text between start & stop is not selected (ie, not high-lighted).

In order to experiment with richedit to see if I could use it, I went into
generic.exw & added an "info" button to the tool bar, & put some text in the
richedit like this:

setText(GText, "this is a line\nthis is a second line\n" &
   "select some text & click the right-most question mark\n" &
   "to see the index of start/finish")

And then in the click on that button event did this:


-- richedit info... behavior
procedure onClick_ToolInfo(integer self, integer even, sequence parms)
    atom found

    found = findText(GText, "click", 0, findDown + findMatchCase +
findWholeWord)
    setIndex(GText, {found,  found + length("click")})

       setText({GStatus,2},"")
       setText({GStatus,2},sprint(found))


end procedure
setHandler (ToolInfo, w32HClick, routine_id( "onClick_ToolInfo" ))

I thought the above should have high-lighted "click" when the button in the
toolbar was clicked on, but while the status bar showed the correct position
of the word, it was not high-lighted.

Using:
Win98 1st ed, Eu 2.3, Win32Lib 59.1.

You can either do that, or you can use this method of selecting text.

include win32lib.ew
constant mywin = create(Window,"RichEdit Text",0,Default,Default,300,200,0),
                riched = create(RichEdit,"",mywin,0,0,300,200,0),
                mFile = create(Menu,"&File",mywin,0,0,0,0,0),
                mSelTex = create(MenuItem,"&Select Text",mFile,0,0,0,0,0),
                mSep1 = create(MenuItem,"-",mFile,0,0,0,0,0),
                mExit = create(MenuItem,"E&xit",mFile,0,0,0,0,0)

procedure onResize_mywin(integer id, integer event, sequence param)
    param = getClientRect(mywin)
    setRect(riched,0,0,param[3],param[4],1)
end procedure
setHandler(mywin,w32HResize,routine_id("onResize_mywin"))

procedure onOpen_mywin(integer id, integer event, sequence param)
    setText(riched,"Hello World, this is a Select Text demo")
end procedure
setHandler(mywin,w32HOpen,routine_id("onOpen_mywin"))

procedure onClick_mSelText(integer id, integer event, sequence param)
    object void
    void = sendMessage(riched,WM_SETSEL,0,15)
end procedure
setHandler(mSelText,w32HClick,routine_id("onClick_mSelText"))

procedure onClick_mExit(integer id, integer event, sequence param)
    closeWindow(mywin)
end procedure
setHandler(mExit,w32HClick,routine_id("onClick_mExit"))

WinMain(mywin,Normal)

This code is untested, seeing as I'm now on Linux, and no longer have 
access to a Windows Computer.  But if I'm right, this should work, minus 
the fact, that it might be another Window Message Constant, but it 
should be something similar to that.

Mario,

Thanks for trying in the blind; WM_SETSEL isn't it, & WM_SETFOCUS didn't
work, & I couldn't find any other constant that looked like it would be the
one either..

But Derek's setFocus() suggestion worked fine.
