Usage

Details

This function will search for Windows handles, for passing to external GUIs or to the arrangeWindows function. Each of the arguments may be a vector of values. These will be treated as follows:

  • The arguments will all be recycled to the same length.
  • The corresponding elements of each argument will be applied in separate searches.
  • The final result will be the union of the windows identified in each of the searches.
If an element of which is "R", only windows belonging to the current R process will be returned. In MDI mode, those will be the child windows within the R GUI frame. In SDI mode, all windows belonging to the process will be included. If the element is "all", then top level windows will be returned. The elements of pattern will be used to make a subset of windows whose title text matches (according to grep) the pattern. If minimized = FALSE, minimized windows will be ignored.

Value

A list of external pointers containing the window handles.

Note

This is only available on Windows.
