Mouse events are represented by <STRONG>KEY_MOUSE</STRONG> pseudo-key values in the <STRONG>wgetch</STRONG> input stream. To make mouse events visible, use the <STRONG>mousemask</STRONG> function. This will set the mouse events to be reported. By de- fault, no mouse events are reported. The function will return a mask to indicate which of the specified mouse events can be reported; on complete failure it returns 0. If oldmask is non-NULL, this function fills the indicated location with the previous value of the given window's mouse event mask. As a side effect, setting a zero mousemask may turn off the mouse pointer; setting a nonzero mask may turn it on. Whether this happens is device-dependent. Here are the mouse event type masks which may be defined: <EM>Name</EM> <EM>Description</EM> --------------------------------------------------------------------- BUTTON1_PRESSED mouse button 1 down BUTTON1_RELEASED mouse button 1 up BUTTON1_CLICKED mouse button 1 clicked BUTTON1_DOUBLE_CLICKED mouse button 1 double clicked BUTTON1_TRIPLE_CLICKED mouse button 1 triple clicked --------------------------------------------------------------------- BUTTON2_PRESSED mouse button 2 down BUTTON2_RELEASED mouse button 2 up BUTTON2_CLICKED mouse button 2 clicked BUTTON2_DOUBLE_CLICKED mouse button 2 double clicked BUTTON2_TRIPLE_CLICKED mouse button 2 triple clicked --------------------------------------------------------------------- BUTTON3_PRESSED mouse button 3 down BUTTON3_RELEASED mouse button 3 up BUTTON3_CLICKED mouse button 3 clicked BUTTON3_DOUBLE_CLICKED mouse button 3 double clicked BUTTON3_TRIPLE_CLICKED mouse button 3 triple clicked --------------------------------------------------------------------- BUTTON4_PRESSED mouse button 4 down BUTTON4_RELEASED mouse button 4 up BUTTON4_CLICKED mouse button 4 clicked BUTTON4_DOUBLE_CLICKED mouse button 4 double clicked BUTTON4_TRIPLE_CLICKED mouse button 4 triple clicked --------------------------------------------------------------------- BUTTON5_PRESSED mouse button 5 down BUTTON5_RELEASED mouse button 5 up BUTTON5_CLICKED mouse button 5 clicked BUTTON5_DOUBLE_CLICKED mouse button 5 double clicked BUTTON5_TRIPLE_CLICKED mouse button 5 triple clicked --------------------------------------------------------------------- BUTTON_SHIFT shift was down during button state change BUTTON_CTRL control was down during button state change BUTTON_ALT alt was down during button state change ALL_MOUSE_EVENTS report all button state changes REPORT_MOUSE_POSITION report mouse movement --------------------------------------------------------------------- Once a class of mouse events have been made visible in a window, calling the <STRONG>wgetch</STRONG> function on that window may re- turn <STRONG>KEY_MOUSE</STRONG> as an indicator that a mouse event has been queued. To read the event data and pop the event off the queue, call <STRONG>getmouse</STRONG>. This function will return <STRONG>OK</STRONG> if a mouse event is actually visible in the given window, <STRONG>ERR</STRONG> otherwise. When <STRONG>getmouse</STRONG> returns <STRONG>OK</STRONG>, the data deposited as y and x in the event structure coordinates will be screen-relative character-cell coordinates. The returned state mask will have exactly one bit set to indicate the event type.⌨️ 快捷键说明
