 Posted: Tue Jun 22, 2004 10:12 am Post subject: slider bar values directly to and editbox or label ?? |
 |
|
If i have mutliple slider bars is there a way to place an edit box or
label next to them and have the slider values tagged directly into the
edit box or lable for user feedback of the current slider values,
without coding an update routine.
Also TIniFile, when you create an infile during a program, say saving
some values, isnt the default creation directory supposed to be the
directory the exe file is running in?
Mine end up being created in the c:winnt directory (win2000) by
default or should you always explicitly place a directory path in the
name string.
thanks for any help

You could create a new component, as decsendant of the sliderbar, and then
add a published member TEdit *EditBox
Then override the OnChange Event and do
OnChangeEvent(TObject *Sender)
{
if(EditBox != 0)
EditBox->Text = IntToStr(Pos);
}

Ini files are stored by default in the WIndows directory, because that is
where they were back in the old days, with Windows 3.11. If you want it in
your current directory, you must specify.

The standard controls do not support that, no. You would have to find a
third-party component (or make your own) in order to do that. Otherwise,
using the slider bar's normal event handler(s) is the only other way. What
you could do, however, is put your edit boxes or labels into an array, and
then set each slider bar's Tag property to the index of the array element
that it should update. Then your event handler could use the Tag of the
triggering slider bar to update the appropriate edit/label that is in the
array.

No. In fact, if you don't specify a full path, the Win32 API will look for
the file relative to the Windows folder instead.

Correct. That is by design, and works that way under all Windows versions.

Yes.
