*WinScrolled*
WinScrolled After scrolling the content of a window or
- resizing a window.
- The pattern is matched against the
- |window-ID|. Both <amatch> and <afile> are
- set to the |window-ID|.
- Non-recursive (the event cannot trigger
- itself). However, if the command causes the
- window to scroll or change size another
+ resizing a window in the current tab page.
+
+ When more than one window scrolled or resized
+ only one WinScrolled event is triggered. You
+ can use the `winlayout()` and `getwininfo()`
+ functions to see what changed.
+
+ The pattern is matched against the |window-ID|
+ of the first window that scrolled or resized.
+ Both <amatch> and <afile> are set to the
+ |window-ID|.
+
+ Only starts triggering after startup finished
+ and the first screen redraw was done.
+
+ Non-recursive: the event will not trigger
+ while executing commands for the WinScrolled
+ event. However, if the command causes a
+ window to scroll or change size, then another
WinScrolled event will be triggered later.
+
Does not trigger when the command is added,
only after the first scroll or resize.
+ *E1312*
+ It is not allowed to change the window layout
+ here (split, close or move windows).
