The _SCREENMOVE statement positions the program window on the desktop using designated coordinates.
Syntax
- _SCREENMOVE {column&, row&|_MIDDLE}
Parameters
- Positions the program window on the desktop using the column& and row& pixel coordinates for the upper left corner.
- _MIDDLE can be used instead to automatically center the program window on the desktop, in any screen resolution.
Description
- The program's SCREEN dimensions may influence the desktop position that can be used to keep the entire window on the screen.
- Use _DESKTOPWIDTH and _DESKTOPHEIGHT to find the current desktop resolution to place the program's window.
- On dual monitors a negative column& position or a value greater than the main screen width can be used to position a window in another monitor.
- A small delay may be necessary when a program first starts up to properly orient the screen on the desktop properly. See _SCREENEXISTS.
- Keyword not supported in Linux versions
Availability
v0.926
all
yes
no
yes
Examples
Example 1: Calculating the border and header offsets by comparing a coordinate move with _MIDDLE by using trial and error.
userwidth& = _DESKTOPWIDTH: userheight& = _DESKTOPHEIGHT 'get current screen resolution SCREEN _NEWIMAGE(800, 600, 256) scrnwidth& = _WIDTH: scrnheight& = _HEIGHT 'get the dimensions of the program screen _SCREENMOVE (userwidth& \ 2 - scrnwidth& \ 2) - 3, (userheight& \ 2 - scrnheight& \ 2) - 29 _DELAY 4 _SCREENMOVE _MIDDLE 'check centering END |
- When positioning the window, offset the position by -3 columns and - 29 rows to calculate the top left corner coordinate.
Example 2: Moving a program window to a second monitor positioned to the right of the main desktop.
wide& = _DESKTOPWIDTH high& = _DESKTOPHEIGHT PRINT wide&; "X"; high& _DELAY 4 _SCREENMOVE wide& + 200, 200 'positive value for right monitor 2 img2& = _SCREENIMAGE wide2& = _WIDTH(img2&) high2& = _HEIGHT(img2&) PRINT wide2&; "X"; high2& _DELAY 4 _SCREENMOVE _MIDDLE 'moves program back to main monitor 1 |
- Notes: Change the _SCREENMOVE column to negative for a left monitor.
