TGTextEntry Class Reference

A TGTextEntry is a one line text input widget.

Changing text in the text entry widget will generate the event: kC_TEXTENTRY, kTE_TEXTCHANGED, widget id, 0. Hitting the enter key will generate: kC_TEXTENTRY, kTE_ENTER, widget id, 0. Hitting the tab key will generate: kC_TEXTENTRY, kTE_TAB, widget id, 0.

This widget has the behaviour e.g. of the "Location" field in web browsers. That includes handling Control/Shift key modifiers and scrolling the text.

enum TGTextEntry::EEchoMode

This enum type describes the ways in which TGTextEntry can display its contents. The currently defined values are:

  • kNormal - display characters as they are entered. This is the default.
  • kNoEcho - do not display anything.
  • kPassword - display asterisks instead of the characters actually entered.

See also SetEchoMode(), GetEchoMode().

enum TGTextEntry::EInsertMode

This enum type describes the way how typed characters are inserted in the text entry. This mode is switched by "Insert" key.

  • kInsert - typed character are inserted (cursor has shape of short line).
  • kReplace - typed characters substitute already typed ones (cursor has the shape of filled rectangle).

enum TGWidget::ETextJustification

This enum type (defined in TGWidget.h) describes the text alignment modes. These modes are valid until text fits the frame width

  • kTextLeft - left-side text alignment
  • kTextRight - right-side text alignment
  • kTextCenterX - center text alignment

The key press event handler converts a key press to some line editor action. Here are the default key bindings:

  • Left Arrow Move the cursor one character leftwards. Scroll the text when cursor is out of frame.
  • Right Arrow Move the cursor one character rightwards Scroll the text when cursor is out of frame.
  • Backspace Deletes the character on the left side of the text cursor and moves the cursor one position to the left. If a text has been marked by the user (e.g. by clicking and dragging) the cursor will be put at the beginning of the marked text and the marked text will be removed.
  • Home Moves the text cursor to the left end of the line. If mark is TRUE text will be marked towards the first position, if not any marked text will be unmarked if the cursor is moved.
  • End Moves the text cursor to the right end of the line. If mark is TRUE text will be marked towards the last position, if not any marked text will be unmarked if the cursor is moved.
  • Delete Deletes the character on the right side of the text cursor. If a text has been marked by the user (e.g. by clicking and dragging) the cursor will be put at the beginning of the marked text and the marked text will be removed.
  • Insert Switches character insert mode.
  • Shift - Left Arrow Mark text one character leftwards
  • Shift - Right Arrow Mark text one character rightwards
  • Control - Left Arrow Move the cursor one word leftwards
  • Control - Right Arrow Move the cursor one word rightwards.
  • Control - Shift - Left Arrow Mark text one word leftwards
  • Control - Shift - Right Arrow Mark text one word rightwards
  • Control-A Move the cursor to the beginning of the line
  • Control-B Move the cursor one character leftwards
  • Control-C Copy the marked text to the clipboard.
  • Control-D Delete the character to the right of the cursor
  • Control-E Move the cursor to the end of the line
  • Control-F Move the cursor one character rightwards
  • Control-H Delete the character to the left of the cursor
  • Control-K Delete marked text if any or delete all characters to the right of the cursor
  • Control-U Delete all characters on the line
  • Control-V Paste the clipboard text into line edit.
  • Control-X Cut the marked text, copy to clipboard.
  • Control-Y Paste the clipboard text into line edit.

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