_client

_client: null;
Source: EPP.L

_client put_to (string a);

abort

abort: modeless_dialog;
Standard dialog box for aborting a print job
Source: ABORT.L

. The application displays this dialog at the beginning of a print
. job and periodically calls the "yield" function to give the user
. the opportunity to select the "Cancel" button. This will call the
. "abort" member function of the class which created the abort dialog.

public: static bool aborting;
Flag for application to monitor to tell when user requested abort

protected: any caller;
Object for the caller - used for calling the "abort" callback

public_read: string line1;
Line of text to display in dialog box

public_read: string line2;
Second line of text

void abort (); Constructor

void abort (window parent, any caller); Constructor to set parent window and object to receive "abort" call

string line1 (string line1); Set the first line of text

string line2 (string line2); Set the second line of text

void ok (); Callback for the "Cancel" button
. Not called directly by the application, this function is called
. automatically when the user selects the "Cancel" button.
. Note: This "ok" instead of "cancel" because the Cancel button is
. the default push button (which always calls "ok".)

bool show (); Reset the "aborting" flag and then show the Abort dialog box

app_window

app_window: window;
The default application window
Source: WINDOW.L

. An application can redefine this class or use as-is.
. The primary intent of this class is for the ::window function
. to create a default application window. Also, the default
. ::main function calls ::window which instantiates this class.
. So, the effect is that you don't need a main function if you
. want to use either the default app_window or if you want to
. define your own app_window class.

void app_window ();

void app_window (string title);

app_window_stub

app_window_stub: null;

apply_button

apply_button: def_push_button;
Standard "Apply" push button control
Source: CONTROL.L

void apply_button (); Constructor

array

array: null;
Dynamic array
Source: ARRAY.L

. A dynamic array initially has no elements. It "grows" and shrinks
. automatically as elements are stored, appended, inserted, and
. deleted.
.
. Note that some member functions such as "put_to" and "find_text"
. are defined in the "null" class since any Liana class can have
. "array-like" behavior as long as that class defines "size" and
. "get" functions.
.
. The default allocation unit size is 13:
. For a 64-byte block there is an 8-byte header plus a 4-byte
. "next" pointer for a total overhead of 12 bytes which leaves
. 52 bytes which is 13 4-byte entries.

public: int block_size;
Allocation unit size
. Space is allocated as needed.
. An additional block of this size is allocated as elements are
. referenced beyond the end of the array.

protected: any current;
Pointer to current fixed_array block

protected: any first;
Pointer to first fixed_array block

protected: any last;
Pointer to last fixed_array block

public_read: int size;
Number of elements
. This is the index of the last element minus 1.
. Any insertions or deletions will automatically adjust this size.

array append_from (array a); Append contents of another array

void array (); Constructor

void array (any element1, array elements...); Constructor to initialize elements of an array

any browser_element_name (int i); Get name of ith element for debug browser
. This is the array index in square brackets.

any browser_element_value (int i); Get value of the ith element for the debug browser
. This is the value of the ith element of the array.

array copy_from (array a); Initialize with contents of another array

long find (any v, long i); Search for a value starting at the ith element
. See also: null::find (v)

any get (long i); Return the ith element

any insert (long i, any v); Insert a new element before the ith element
. Returns the new element value.

any put (long i, any v); Replace the value of the ith element
. See also: null::put_to (v)

any remove (long i, long n); Delete "n" elements starting with the ith element
. Returns this object.

long internal_id (); Returns the internal 24-bit ID for a name or object's class name
. Returns id for a name string, object's class, or 0 for other values.

bool is_a (string class_name); Returns true if this object is of specified class or a derived class

bool is_a_id (long class_name_id); Returns true if this object is of specified class id or a derived class
. The argument is the internal id for the class name (see internal_id.)
. This is faster than "is_a" since the class name string does not have
. to be looked up to get the internal id.

string member_name (int i);

long msize (); The allocated size of this object
. This is the amount of data space actually available, regardless of
. the amount that was originally requested.
. For user-defined objects that do not redefine this function, it
. calls the "size" member function. For example, calling msize for
. an array is the same as calling the size member function.

string name (); Dummy function returning the "name" of this object
. This dummy name is this.source_format.

bool not (); Dummy function implementing the "!" operator
. It returns "false" because it will only be called for a user-defined
. class (which is therefore non-null by definition.) Note that the
. predefined types (null, bool, int, real, string) are handled
. automatically by the runtime interpreter.

. Callback Functions
. ------------------
.
. These are functions defined in the application by classes used
. to define the object stored in the "object" data member.
.
. The callback functions for keys all end with "_key". They are
. also optionally prefixed with the following modifiers:
.
. shift_xxx_key // Shift key
. ctrl_xxx_key // Control key
. alt_xxx_key // Alt key
. ctrl_shift_xxx_key // Control and Shift keys
. ctrl_alt_xxx_key // Control and Alt and Shift keys
. alt_shift_xxx_key // Alt and Shift keys
. ctrl_alt_shift_xxx_key // Control and Alt and Shift keys
.
. For example:
.
. bool shift_f6_key ()
. {
. message ("Got the Shift+F6 key");
. }
.
. Key callback functions should return false if they want normal
. processing (as if not called) to occur. Return null (or no return)
. if the normal processing should be bypassed.
.
.
. bool backspace_key ()
. bool ctrl_a_key ()
. bool ctrl_z_key ()
. bool delete_key ()
. bool down_key ()
. bool end_key ()
. bool enter_key ()
. bool escape_key ()
. bool f1_key ()
. ...
. bool f24_key ()
. bool home_key ()
. bool insert_key ()
. bool left_key ()
. bool num_lock_key ()
. bool page_down_key ()
. bool page_up_key ()
. bool pause_key ()
. bool print_screen_key ()
. bool right_key ()
. bool scroll_lock_key ()
. bool tab_key ()
. bool up_key ()
.
. These functions are called when the user presses the following keys:
.
. Backspace
. Delete
. down arrow (cursor)
. End
. Enter
. Esc (escape)
. Home
. Insert
. left arrow (cursor)
. Num Lock
. Page Down
. Page Up
. Pause
. Print Scrn
. right arrow (cursor)
. Scroll Lock
. Tab
. up arrow (cursor)
.
. ... TBD ...
