arrangeWindows | R Documentation |
This function allows you to tile or cascade windows, or to minimize or
restore them (on Windows, i.e. when (.Platform$OS.type == "windows")
).
This may include windows not “belonging” to R.
arrangeWindows(action, windows, preserve = TRUE, outer = FALSE)
action |
a character string, the action to perform on the
windows. The choices are
|
windows |
a |
preserve |
If |
outer |
This argument is only used in MDI mode. If |
The actions are as follows:
"vertical"
Tile vertically.
"horizontal"
Tile horizontally.
"cascade"
Cascade the windows.
"minimize"
Minimize all of the windows.
"restore"
Restore all of the windows to normal size (not minimized, not maximized).
The tiling and cascading are done by the standard Windows API functions, but unlike those functions,
they will apply to all of the windows in the windows
list.
By default, windows
is set to the result of
getWindowsHandles()
(with one exception described
below). This will select windows belonging to the current R process.
However, if the global environment contains a variable named
.arrangeWindowsDefaults
, it will be used as the argument list
instead. See the getWindowsHandles
man page for a
discussion of the optional arguments to that function.
When action = "restore"
is used with windows
unspecified,
minimized = TRUE
is added to the argument list of
getWindowsHandles
so that minimized windows will be restored.
In MDI mode, by default tiling and cascading will happen within the R
GUI frame. However, if outer = TRUE
, tiling is done on the system
desktop. This will generally not give desirable results if any R child
windows are included within windows
.
This function is called for the side effect of arranging the windows. The list of window handles is returned invisibly.
This is only available on Windows.
