Detailed Description

Handling windows of selected threads.

Date:: 01/15/2004

Author:: Jork Loeser <jork.loeser@inf.tu-dresden.de>

Locking order: list first (list_lock()), disp then (lock_disp()).

Function Documentation

static load_display_t* disp_alloc ( void ) [static]

Allocate a new display.

This function returns a new display structure. The fields win, grid and name are already filled in. If it is called the first time (i.e., list_count==0), main_disp is returned.

Postcondition:: the returned display is in init state, unlocked, and not linked

Return values:

	!0	Ok
	<0	Error

load_display_t* disp_by_nr ( int id )

Return a locked display by its number.

This function uses the list-lock.

Referenced by scope_create(), select_all_callback(), select_callback(), sort_callback(), subwindow_create(), subwindow_name_callback(), and subwindow_thread_callback().

static void disp_free ( load_display_t * disp ) [static]

Free a load display with all its items.

Precondition:: No references to the display are hanging around, and that the disp is not on the list anymore.
disp is unlocked.

Referenced by subwindow_create().

static void disp_insert ( load_display_t * disp ) [static]

Insert a disp into the list.

This function uses the list-lock

Referenced by subwindow_create().

static load_display_t* disp_unlink ( int id ) [static]

Remove a disp from the list.

This function removes the load-display specified by idx from the list.

This function uses the list-lock.

Postcondition:: The disp is locked, state is LD_STATE_INIT

int do_nonmouse_event	(	dope_event *	ev,
		void *	arg
	)			`[inline]`

Check if it is a non-mouse event and call press_callback if so.

If the event is not a mouse-event, it is probably a keyboard-event, meant for the press_callback. An event-specific bind (press-mouse, press-keyboard) would be nice here.

Returns:: 1 if it was a non-mouse event, 0 else

void select_all_callback	(	dope_event *	ev,
		void *	arg
	)			`[static]`

Callback for Top "X" select-button press.

Parameters:

arg

a jtop_callback_t type, which win and idx set. win is the window-id, idx is the nr of the row (0..)

As we get all pres-events of the label (including keyboard), we have to check this first and conditionally jump to press_callback.

static void sort_callback	(	dope_event *	ev,
		void *	arg
	)			`[static]`

Callback for setting sort-orders in windows.

Parameters:

arg

a jtop_callback_t type, which win and idx set. win is the window-id, idx is the sort_t

int subwindow_create ( int id_parent )

Generate a new window from the selected threads of a parent.

No reference is held to the parent, so the parent can be destroyed when this function returned.

Parameters:

id_parent

Id of the parent disp. Used for getting the switch- setting. Set it to -1 to create the root-window.

void subwindow_name_callback	(	dope_event *	ev,
		void *	arg
	)

Callback for name-label press.

Left key toggles selection, right key disables.

Parameters:

arg

a jtop_callback_t type, which win and idx set. win is the window-id, idx is the nr of the row (0..)

As we get all pres-events of the label (including keyboard), we have to check this first and conditionally jump to press_callback.

References disp_by_nr(), and do_nonmouse_event().

void subwindow_thread_callback	(	dope_event *	ev,
		void *	arg
	)

Callback for thread-label press.

This callback selects threads that are similar to the clicked one. With L4, this is the same task, with Linux, this is something else.

Left key toggles selection, right key disables.

Parameters:

arg

a jtop_callback_t type, which win and idx set. win is the window-id, idx is the nr of the row (0..)

As we get all pres-events of the label (including keyboard), we have to check this first and conditionally jump to press_callback.
