95 | =head2 Extension Objects |
|
|
96 | |
|
|
97 | Every perl extension is a perl class. A separate perl object is created |
|
|
98 | for each terminal, and each terminal has its own set of extension objects, |
|
|
99 | which are passed as the first parameter to hooks. So extensions can use |
|
|
100 | their C<$self> object without having to think about clashes with other |
|
|
101 | extensions or other terminals, with the exception of methods and members |
|
|
102 | that begin with an underscore character C<_>: these are reserved for |
|
|
103 | internal use. |
|
|
104 | |
|
|
105 | Although it isn't a C<urxvt::term> object, you can call all methods of the |
|
|
106 | C<urxvt::term> class on this object. |
|
|
107 | |
|
|
108 | Additional methods only supported for extension objects are described in |
|
|
109 | the C<urxvt::extension> section below. |

290 | resource in the urxvt(1) manpage). |
|
|
291 | |
|
|
292 | The event is simply the action string. This interface is going away in |
|
|
293 | preference to the C<on_action> hook. |
|
|
294 | |
|
|
295 | =item on_resize_all_windows $term, $new_width, $new_height |
|
|
296 | |
|
|
297 | Called just after the new window size has been calculated, but before |
|
|
298 | windows are actually being resized or hints are being set. If this hook |
|
|
299 | returns a true value, setting of the window hints is being skipped. |
|
|
300 | |
|
|
301 | =item on_x_event $term, $event |
|
|
302 | |
|
|
303 | Called on every X event received on the vt window (and possibly other |
|
|
304 | windows). Should only be used as a last resort. Most event structure |
|
|
305 | members are not passed. |
|
|
306 | |
|
|
307 | =item on_root_event $term, $event |
|
|
308 | |
|
|
309 | Like C<on_x_event>, but is called for events on the root window. |
|
|
310 | |
|
|
311 | =item on_focus_in $term |
|
|
312 | |
|
|
313 | Called whenever the window gets the keyboard focus, before rxvt-unicode |
|
|
314 | does focus in processing. |
|
|
315 | |
|
|
316 | =item on_focus_out $term |
|
|
317 | |
|
|
318 | Called whenever the window loses keyboard focus, before rxvt-unicode does |
|
|
319 | focus out processing. |
|

|
|
336 | |
|
|
337 | =item on_unmap_notify $term, $event |
|
|
338 | |
|
|
339 | Called whenever the corresponding X event is received for the terminal. If |
|
|
340 | the hook returns true, then the event will be ignored by rxvt-unicode. |
|
|
341 | |
|
|
342 | The event is a hash with most values as named by Xlib (see the XEvent |
|
|
343 | manpage), with the additional members C<row> and C<col>, which are the |
|
|
344 | (real, not screen-based) row and column under the mouse cursor. |
|
|
345 | |
|
|
346 | C<on_key_press> additionally receives the string rxvt-unicode would |
|
|
347 | output, if any, in locale-specific encoding. |

352 | |
|
|
353 | =item on_wm_delete_window $term, $event |
|
|
354 | |
|
|
355 | Called when various types of ClientMessage events are received (all with |
|
|
356 | format=32, WM_PROTOCOLS or WM_PROTOCOLS:WM_DELETE_WINDOW). |
|
|
357 | |
|

974 | =head2 The C<urxvt::anyevent> Class |
|
|
975 | |
|
|
976 | The sole purpose of this class is to deliver an interface to the |
|
|
977 | C<AnyEvent> module - any module using it will work inside urxvt without |
|
|
978 | further programming. The only exception is that you cannot wait on |
|
|
979 | condition variables, but non-blocking condvar use is ok. |
|
|
980 | |
|
|
981 | In practical terms this means is that you cannot use blocking APIs, but |
|
|
982 | the non-blocking variant should work. |

1163 | C<start> hooks will be called before this call returns, and are free to |

1272 | class name, i.e. C<< $term->x_resource ("boldFont") >> should return the |

1276 | Extensions that define extra resource or command line arguments also need |

1277 | to call this method to access their values. |

|
1278 | |
|

1279 | If the method is called on an extension object (basically, from an |
|
|
1280 | extension), then the special prefix C<%.> will be replaced by the name of |
|
|
1281 | the extension and a dot, and the lone string C<%> will be replaced by the |

1282 | extension name itself. This makes it possible to code extensions so you |
|

1283 | can rename them and get a new set of commandline switches and resources |
|
|
1284 | without having to change the actual code. |

1286 | This method should only be called during the C<on_start> hook, as there is |

1293 | and returns C<1> for true values, C<0> for false values and C<undef> if |
|
|
1294 | the resource or option isn't specified. |
|
|
1295 | |
|
