25// TGTextEntry //
26// //
27// A TGTextEntry is a one line text input widget. //
28// //
29// Changing text in the text entry widget will generate the event: //
30// kC_TEXTENTRY, kTE_TEXTCHANGED, widget id, 0. //
31// Hitting the enter key will generate: //
32// kC_TEXTENTRY, kTE_ENTER, widget id, 0. //
33// Hitting the tab key will generate: //
34// kC_TEXTENTRY, kTE_TAB, widget id, 0. //
35// //
36// This widget has the behaviour e.g. of the "Location" field in //
37// netscape. That includes handling Control/Shift key modifiers and //
38// scrolling the text. //
39//
40//
41// enum TGTextEntry::EEchoMode
42//
43// This enum type describes the ways in which TGTextEntry can display
44// its contents. The currently defined values are:
45//
46/*
47<ul>
48<li> kNormal - display characters as they are entered. This is the default.
49<li> kNoEcho - do not display anything.
50<li> kPassword - display asterisks instead of the characters actually entered.
51</ul>
52*/
53//
54// See also SetEchoMode(), GetEchoMode().
55//
56// enum TGTextEntry::EInsertMode
57//
58// This enum type describes the way how typed characters are
59// inserted in the text entry. This mode is switched by "Insert" key.
60//
61/*
62<ul>
63<li> kInsert - typed character are inserted (cursor has shape of short line).
64<li> kReplace - typed characters substitute already typed ones
65 (cursor has the shape of filled rectangle).
66</ul>
67*/
68//
69//
70// enum TGWidget::ETextJustification
71//
72// This enum type (defined in TGWidget.h) describes the text alignment modes.
73// These modes are valid until text fits the frame width
74//
75/*
76<ul>
77<li> kTextLeft - left-side text alignment
78<li> kTextRight - right-side text alignment
79<li> kTextCenterX - center text alignment
80</ul>
81*/
82//
83//
84//
85// The key press event handler converts a key press to some line editor action.
86// Here are the default key bindings:
87//
88/*
89<ul>
90<li><i> Left Arrow </i>
91 Move the cursor one character leftwards.
92 Scroll the text when cursor is out of frame.
93<li><i> Right Arrow </i>
94 Move the cursor one character rightwards
95 Scroll the text when cursor is out of frame.
96<li><i> Backspace </i>
97 Deletes the character on the left side of the text cursor and moves the
98 cursor one position to the left. If a text has been marked by the user
99 (e.g. by clicking and dragging) the cursor will be put at the beginning
100 of the marked text and the marked text will be removed.
101<li><i> Home </i>
102 Moves the text cursor to the left end of the line. If mark is TRUE text
103 will be marked towards the first position, if not any marked text will
104 be unmarked if the cursor is moved.
105<li><i> End </i>
106 Moves the text cursor to the right end of the line. If mark is TRUE text
107 will be marked towards the last position, if not any marked text will
108 be unmarked if the cursor is moved.
109<li><i> Delete </i>
110 Deletes the character on the right side of the text cursor. If a text
111 has been marked by the user (e.g. by clicking and dragging) the cursor
112 will be put at the beginning of the marked text and the marked text will
113 be removed.
114<li><i> Insert </i>
115 Switches character insert mode.
116<li><i> Shift - Left Arrow </i>
117 Mark text one character leftwards
118<li><i> Shift - Right Arrow </i>
119 Mark text one character rightwards
120<li><i> Control - Left Arrow </i>
121 Move the cursor one word leftwards
122<li><i> Control - Right Arrow </i>
123 Move the cursor one word rightwards.
124<li><i> Control - Shift - Left Arrow </i>
125 Mark text one word leftwards
126<li><i> Control - Shift - Right Arrow </i>
127 Mark text one word rightwards
128<li><i> Control-A </i>
129 Move the cursor to the beginning of the line
130<li><i> Control-B </i>
131 Move the cursor one character leftwards
132<li><i> Control-C </i>
133 Copy the marked text to the clipboard.
134<li><i> Control-D </i>
135 Delete the character to the right of the cursor
136<li><i> Control-E </i>
137 Move the cursor to the end of the line
138<li><i> Control-F </i>
139 Move the cursor one character rightwards
140<li><i> Control-H </i>
141 Delete the character to the left of the cursor
142<li><i> Control-K </i>
143 Delete marked text if any or delete all
144 characters to the right of the cursor
145<li><i> Control-U </i>
146 Delete all characters on the line
147<li><i> Control-V </i>
148 Paste the clipboard text into line edit.
149<li><i> Control-X </i>
150 Cut the marked text, copy to clipboard.
151<li><i> Control-Y </i>
152 Paste the clipboard text into line edit.

154All other keys with valid ASCII codes insert themselves into the line.
