{{DISPLAYTITLE:_MOUSESHOW}}
|
|
The '''_MOUSESHOW''' statement displays the mouse cursor and can determine its shape in GL.

{{PageSyntax}}
|
|
::: '''_MOUSESHOW''' [''cursortype$'']
|
|
|
|
|
|
''Description:''
|
|
* Simply use the statement whenever [[_MOUSEHIDE]] has been used previously.
|
|
* In '''QB64 GL''' the following [[STRING]] cursor types can be displayed:
|
|
::_MOUSESHOW "LINK" will display an upward pointing hand cursor used to denote hypertext
|
|
::_MOUSESHOW "TEXT" will display the I cursor often used in text entry areas
|
|
::_MOUSESHOW "CROSSHAIR" will display a crosshair cursor
|
|
::_MOUSESHOW "VERTICAL" will display vertical arrow cursor for movement
|
|
::_MOUSESHOW "HORIZONTAL" will display horizontal arrow cursor for movement
|
|
::_MOUSESHOW "TOPLEFT_BOTTOMRIGHT" will display bottom diagonal arrow cursor for movement
|
|
::_MOUSESHOW "TOPRIGHT_BOTTOMLEFT" will display bottom diagonal arrow cursor for movement
|
|
::_MOUSESHOW "DEFAULT" can be used after a mouse cursor statement above was previously used.
|
|
* This statement will also disable [[_MOUSEMOVEMENTX]] or [[_MOUSEMOVEMENTY]] relative mouse movement reads.
|
|
* The mouse cursor will not interfere with any print or graphic screen changes in '''QB64'''.
|
|
* _MOUSEHIDE statements do not accumulate like they did with [[ABSOLUTE]] or [[INTERRUPT]] in Qbasic.
|
|

''Example 1:'' '''QB64 GL''' allows special cursors to be displayed by using special string parameters:

: '''Note:''' There is no hourglass, stopwatch or spinning colorful wheel in the list. The fact is that these typically only appear in a program when something has gone terribly wrong and the program has crashed or frozen.
