Functions for wxCaret class
A caret is a blinking cursor showing the position where the typed text will
appear. Text controls usually have their own caret but wxCaret
provides a
way to use a caret in other windows.
Currently, the caret appears as a rectangle of the given size. In the future, it will be possible to specify a bitmap to be used for the caret shape.
A caret is always associated with a window and the current caret can be
retrieved using wxWindow:getCaret/1
. The same caret can't be reused in two
different windows.

Summary
Functions
Creates a caret with the given size (in pixels) and associates it with the
window
(same as the equivalent constructors).
Destroys the object.
Returns the blink time which is measured in milliseconds and is the time elapsed between 2 inversions of the caret (blink time of the caret is the same for all carets, so this functions is static).
Get the window the caret is associated with.
Hides the caret, same as Show(false).
Returns true if the caret was created successfully.
Returns true if the caret is visible and false if it is permanently hidden (if it is blinking and not shown currently but will be after the next blink, this method still returns true).
Move the caret to given position (in logical coordinates).
Creates a caret with the given size (in pixels) and associates it with the
window
.
Sets the blink time for all the carets.
Changes the size of the caret.
Shows or hides the caret.
Types
-type wxCaret() :: wx:wx_object().
Functions
-spec create(This, Window, Size) -> boolean() when This :: wxCaret(), Window :: wxWindow:wxWindow(), Size :: {W :: integer(), H :: integer()}.
-spec create(This, Window, Width, Height) -> boolean() when This :: wxCaret(), Window :: wxWindow:wxWindow(), Width :: integer(), Height :: integer().
Creates a caret with the given size (in pixels) and associates it with the
window
(same as the equivalent constructors).
-spec destroy(This :: wxCaret()) -> ok.
Destroys the object.
-spec getBlinkTime() -> integer().
Returns the blink time which is measured in milliseconds and is the time elapsed between 2 inversions of the caret (blink time of the caret is the same for all carets, so this functions is static).
-spec getWindow(This) -> wxWindow:wxWindow() when This :: wxCaret().
Get the window the caret is associated with.
-spec hide(This) -> ok when This :: wxCaret().
Hides the caret, same as Show(false).
Returns true if the caret was created successfully.
Returns true if the caret is visible and false if it is permanently hidden (if it is blinking and not shown currently but will be after the next blink, this method still returns true).
Move the caret to given position (in logical coordinates).
-spec new(Window, Size) -> wxCaret() when Window :: wxWindow:wxWindow(), Size :: {W :: integer(), H :: integer()}.
-spec new(Window, Width, Height) -> wxCaret() when Window :: wxWindow:wxWindow(), Width :: integer(), Height :: integer().
Creates a caret with the given size (in pixels) and associates it with the
window
.
-spec setBlinkTime(Milliseconds) -> ok when Milliseconds :: integer().
Sets the blink time for all the carets.
Warning: Under Windows, this function will change the blink time for all carets permanently (until the next time it is called), even for carets in other applications.
See: getBlinkTime/0
-spec setSize(This, Width, Height) -> ok when This :: wxCaret(), Width :: integer(), Height :: integer().
Changes the size of the caret.
-spec show(This) -> ok when This :: wxCaret().
Shows or hides the caret.
Notice that if the caret was hidden N times, it must be shown N times as well to reappear on the screen.
