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 + default, 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: + + <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 + 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 + return <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. + + The <STRONG>ungetmouse</STRONG> function behaves analogously to <STRONG>ungetch</STRONG>. + It pushes a <STRONG>KEY_MOUSE</STRONG> event onto the input queue, and + associates with that event the given state data and + screen-relative character-cell coordinates. + + The <STRONG>wenclose</STRONG> function tests whether a given pair of + screen-relative character-cell coordinates is enclosed by + a given window, returning TRUE if it is and FALSE other- + wise. It is useful for determining what subset of the + screen windows enclose the location of a mouse event. + + The <STRONG>wmouse_trafo</STRONG> function transforms a given pair of coor- + dinates from stdscr-relative coordinates to screen-rela- + tive coordinates or vice versa. Please remember, that + stdscr-relative coordinates are not always identical to + screen-relative coordinates due to the mechanism to + reserve lines on top or bottom of the screen for other + purposes (ripoff() call, see also slk_... functions). If + the parameter <STRONG>to_screen</STRONG> is <STRONG>TRUE</STRONG>, the pointers <STRONG>pY,</STRONG> <STRONG>pX</STRONG> must + reference the coordinates of a location inside the window + <STRONG>win</STRONG>. They are converted to screen-relative coordinates + and returned through the pointers. If the conversion was + successful, the function returns <STRONG>TRUE</STRONG>. If one of the + parameters was NULL or the location is not inside the win- + dow, <STRONG>FALSE</STRONG> is returned. If <STRONG>to_screen</STRONG> is <STRONG>FALSE</STRONG>, the point- + ers <STRONG>pY,</STRONG> <STRONG>pX</STRONG> must reference screen-relative coordinates. + They are converted to stdscr-relative coordinates if the + window <STRONG>win</STRONG> encloses this point. In this case the function + returns <STRONG>TRUE</STRONG>. If one of the parameters is NULL or the + point is not inside the window, <STRONG>FALSE</STRONG> is returned. Please + notice, that the referenced coordinates are only replaced + by the converted coordinates if the transformation was + successful. + + The <STRONG>mouseinterval</STRONG> function sets the maximum time (in thou- + sands of a second) that can elapse between press and + release events for them to be recognized as a click. Use + <STRONG>mouseinterval(-1)</STRONG> to disable click resolution. This func- + tion returns the previous interval value. The default is + one sixth of a second. + + Note that mouse events will be ignored when input is in + cooked mode, and will cause an error beep when cooked mode + is being simulated in a window by a function such as <STRONG>get-</STRONG> + <STRONG>str</STRONG> that expects a linefeed for input-loop termination. + + + +</PRE> +<H2>RETURN VALUE</H2><PRE> + <STRONG>getmouse</STRONG>, <STRONG>ungetmouse</STRONG> and <STRONG>mouseinterval</STRONG> return the integer + <STRONG>ERR</STRONG> upon failure or <STRONG>OK</STRONG> upon successful completion. <STRONG>mouse-</STRONG> + <STRONG>mask</STRONG> returns the mask of reportable events. <STRONG>wenclose</STRONG> and + <STRONG>wmouse_trafo</STRONG> are boolean functions returning <STRONG>TRUE</STRONG> or <STRONG>FALSE</STRONG> + depending on their test result. + + +</PRE> +<H2>PORTABILITY</H2><PRE> + These calls were designed for <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>, and are not + found in SVr4 curses, 4.4BSD curses, or any other previous + version of curses. + + The feature macro <STRONG>NCURSES_MOUSE_VERSION</STRONG> is provided so the + preprocessor can be used to test whether these features + are present (its value is 1). If the interface is + changed, the value of <STRONG>NCURSES_MOUSE_VERSION</STRONG> will be incre- + mented. + + The order of the <STRONG>MEVENT</STRONG> structure members is not guaran- + teed. Additional fields may be added to the structure in + the future. + + Under <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>, these calls are implemented using + either xterm's built-in mouse-tracking API or Alessandro + Rubini's gpm server. If you are using something other + than xterm and there is no gpm daemon running on your + machine, mouse events will not be visible to <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG> + (and the <STRONG>wmousemask</STRONG> function will always return <STRONG>0</STRONG>). + The z member in the event structure is not presently used. + It is intended for use with touch screens (which may be + pressure-sensitive) or with 3D-mice/trackballs/power + gloves. + + +</PRE> +<H2>BUGS</H2><PRE> + Mouse events under xterm will not in fact be ignored dur- + ing cooked mode, if they have been enabled by <STRONG>wmousemask</STRONG>. + Instead, the xterm mouse report sequence will appear in + the string read. + + Mouse events under xterm will not be detected correctly in + a window with its keypad bit off, since they are inter- + preted as a variety of function key. Your terminfo + description must have <STRONG>kmous</STRONG> set to "\E[M" (the beginning + of the response from xterm for mouse clicks). + + Because there are no standard terminal responses that + would serve to identify terminals which support the xterm + mouse protocol, <STRONG>ncurses</STRONG> assumes that if your $TERM envi- + ronment variable contains "xterm", or <STRONG>kmous</STRONG> is defined in + the terminal description, then the terminal may send mouse + events. + + +</PRE> +<H2>SEE ALSO</H2><PRE> + <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>. + + + + + + + + + + + + + + + + + + + + + + + + + + + + +</PRE> +<HR> +<ADDRESS> +Man(1) output converted with +<a href="http://www.oac.uci.edu/indiv/ehood/man2html.html">man2html</a> +</ADDRESS> +</BODY> +</HTML> |
