Detailed Description

This is a particular kind of PGItem that handles simple one-line or short multi-line text entries, of the sort where the user can type any string.

A PGEntry does all of its internal manipulation on a wide string, so it can store the full Unicode character set. The interface can support either the wide string getters and setters, or the normal 8-bit string getters and setters, which use whatever encoding method is specified by the associated TextNode.

Member Function Documentation

void PGEntry::accept ( const MouseWatcherParameter param)
virtual

This is a callback hook function, called whenever the entry is accepted by the user pressing Enter normally.

Definition at line 473 of file pgEntry.cxx.

Referenced by press().

void PGEntry::accept_failed ( const MouseWatcherParameter param)

This is a callback hook function, called whenever the user presses Enter but we can't accept the input.

void PGEntry::clear_cursor_def ( )

References NodePath::attach_new_node(), and NodePath::remove_node().

Referenced by setup_minimal().

bool PGEntry::cull_callback ( CullTraverser trav,
CullTraverserData data 
)
virtual

This function will be called during the cull traversal to perform any additional operations that should be performed at cull time.

This may include additional manipulation of render state or additional visible/invisible decisions, or any other arbitrary operation.

Note that this function will *not* be called unless set_cull_callback() is called in the constructor of the derived class. It is necessary to call set_cull_callback() to indicated that we require cull_callback() to be called.

By the time this function is called, the node has already passed the bounding-volume test for the viewing frustum, and the node's transform and state have already been applied to the indicated CullTraverserData object.

The return value is true if this node should be visible, or false if it should be culled.

Reimplemented from PGItem.

bool PGEntry::is_wtext ( ) const

Returns true if any of the characters in the string returned by get_wtext() are out of the range of an ASCII character (and, therefore, get_wtext() should be called in preference to get_text()).

Returns a newly-allocated Node that is a shallow copy of this one.

It will be a different Node pointer, but its internal data may or may not be shared with that of the original Node.

void PGEntry::overflow ( const MouseWatcherParameter param)

This is a callback hook function, called whenever the entry is overflowed because the user attempts to type too many characters, exceeding either set_max_chars() or set_max_width().

void PGEntry::set_active ( bool  active)

Toggles the active/inactive state of the entry.

In the case of a PGEntry, this also changes its visual appearance.

void PGEntry::set_blink_rate ( PN_stdfloat  blink_rate)
inline

Sets the number of times per second the cursor will blink while the entry has keyboard focus.

If this is 0, the cursor does not blink, but is held steady.

void PGEntry::set_candidate_active ( const string &  candidate_active)
inline

Specifies the name of the TextProperties structure added to the TextPropertiesManager that will be used to render candidate strings from the IME, used for typing characters in east Asian languages.

Each candidate string represents one possible way to interpret the sequence of keys the user has just entered; it should not be considered typed yet, but it is important for the user to be able to see what he is considering entering.

This particular method sets the properties for the subset of the current candidate string that the user can actively scroll through.

void PGEntry::set_cursor_keys_active ( bool  flag)
inline

Sets whether the arrow keys (and home/end) control movement of the cursor.

If true, they are active; if false, they are ignored.

Definition at line 335 of file pgEntry.I.

void PGEntry::set_cursor_position ( int  position)
inline

Sets the current position of the cursor.

This is the position within the text at which the next letter typed by the user will be inserted; normally it is the same as the length of the text.

void PGEntry::set_max_chars ( int  max_chars)
inline

Sets the maximum number of characters that may be typed into the entry.

This is a limit on the number of characters, as opposed to the width of the entry; see also set_max_width().

If this is 0, there is no limit.

void PGEntry::set_max_width ( PN_stdfloat  max_width)
inline

Sets the maximum width of all characters that may be typed into the entry.

This is a limit on the width of the formatted text, not a fixed limit on the number of characters; also set_max_chars().

If this is 0, there is no limit.

If _num_lines is more than 1, rather than being a fixed width on the whole entry, this becomes instead the wordwrap width (and the width limit on the entry is essentially _max_width * _num_lines).

void PGEntry::set_num_lines ( int  num_lines)
inline

Sets the number of lines of text the PGEntry will use.

This only has meaning if _max_width is not 0; _max_width indicates the wordwrap width of each line.

void PGEntry::set_obscure_mode ( bool  flag)
inline

Specifies whether obscure mode should be enabled.

In obscure mode, a string of asterisks is displayed instead of the literal text, e.g. for entering passwords.

In obscure mode, the width of the text is computed based on the width of the string of asterisks, not on the width of the actual text. This has implications on the maximum length of text that may be entered if max_width is in effect.

Definition at line 368 of file pgEntry.I.

void PGEntry::set_overflow_mode ( bool  flag)
inline

Specifies whether overflow mode should be enabled.

In overflow mode, text can overflow the boundaries of the Entry element horizontally.

Overflow mode only works when the number of lines is 1.

Definition at line 399 of file pgEntry.I.

bool PGEntry::set_text ( const string &  text)
inline

Changes the text currently displayed within the entry.

This uses the Unicode encoding currently specified for the "focus" TextNode; therefore, the TextNode must exist before calling set_text().

The return value is true if all the text is accepted, or false if some was truncated (see set_max_width(), etc.).

void PGEntry::set_text_def ( int  state,

Changes the TextNode that will be used to render the text within the entry when the entry is in the indicated state.

The default if nothing is specified is the same TextNode returned by PGItem::get_text_node().

bool PGEntry::set_wtext ( const wstring &  wtext)

void PGEntry::setup ( PN_stdfloat  width,
int  num_lines

Sets up the entry for normal use.

The width is the maximum width of characters that will be typed, and num_lines is the integer number of lines of text of the entry. Both of these together determine the size of the entry, based on the TextNode in effect.
