The text widget provides a multi-line text editing control.
The widget supports both clipboard for cut-and-paste operations, as well as drag and drop of text. Text may be edited interactively by the user, or changed through the programmatic interface.
During interactive editing, the text widget notifies its target of changes to the current cursor location by issueing SEL_CHANGED callbacks. If text is inserted, deleted, or replaced, the widget will send SEL_INSERTED, SEL_DELETED, or SEL_REPLACED messages, and pass along an FXTextChange to indicate what changes were made to the text buffer, in sufficient detail for recording undo and redo info.
When selections are made, SEL_SELECTED or SEL_DESELECTED messages are issued, passing along the range of text affected by the change in selection.
As the cursor is being moved, matching parentheses, brackets, and braces may be highlighted for a short time if the brace-matching feature has been enabled.
An auto-indent feature, enabled by TEXT_AUTOINDENT flag, will automatically enter a number of spaces if a newline is entered, starting new text entry at the same level of indent as the previous line.
When styled mode is turned on, the text widget will maintain a parallel style-buffer along side the text-buffer. This style buffer is used to index into a style table (FXHiliteStyle), which describes what colors and visual attributes are to be used to draw the each character in the text buffer.
When text is added to the widget programmatically, a style index may be passed in to apply to the newly added text. It is also possible to change the style of the text without changing the text itself. This could be used to form the basis of a colorizing text editor, for example.
The first entry in the style table corresponds to a style index of 1. Style index 0 is used for the default text style, the style that would be shown if the styled mode is not in effect.
In a typical scenario, the contents of the style buffer is either directly written when the text is added to the widget, or is continually modified by editing the text via syntax-based highlighting engine which colors the text based on syntactical patterns.
The text widget has several controlling flags which affect its behaviour and display. TEXT_READONLY sets the widget in read-only mode. In this mode, the contents of the widget may only be changed programmatically, although it is possible for the user to select and paste out of the text buffer. The TEXT_WORDWRAP flag turns on line-wrapping. Normally, long lines extend past the right-hand side of the visible buffer. In wrap mode, text is folded at natural break points (breakable spaces, tabs, etc). The default wrap mode is a fluid wrap, that is, the text is reflowed as the widget is resized. The flag TEXT_FIXEDWRAP disables the fluid wrap mode and makes the widget wrap at a fixed column, regardless of the width of the widget. The TEXT_OVERSTRIKE mode causes text entered by the user to overstrike already existing text, instead of inserting new next. This mode can be toggled interactively by hitting the INS key on the keyboard. The flag TEXT_NO_TABS causes a TAB key to be replaced by the appropriate number of spaces when entered interactively; however, the user can still enter a TAB by entering Ctrl+TAB. Finally, the TEXT_SHOWACTIVE mode will cause the line containing the current cursor location to be highlighted. This makes it easier to find the insertion point when scrolling back and forth a large document.

| FXbool FX::FXText::findText | ( | const FXString & | string, |
| FXint * | beg = NULL, |

| FXint * | end = NULL, |

| FXuint | flags = SEARCH_FORWARD|SEARCH_WRAP|SEARCH_EXACT, |

| ) |
Search for string in text buffer, returning the extent of the string in beg and end.
The search starts from the given starting position, scans forward (SEARCH_FORWARD) or backward (SEARCH_BACKWARD), and wraps around if SEARCH_WRAP has been specified. The search type is either a plain search (SEARCH_EXACT), case insensitive search (SEARCH_IGNORECASE), or regular expression search (SEARCH_REGEX). For regular expression searches, capturing parentheses are used if npar is greater than 1; in this case, the number of entries in the beg[], end[] arrays must be npar also. If either beg or end or both are NULL, internal arrays are used. [This API is still subject to change!!]
| void FX::FXText::setHiliteMatchTime | ( | FXTime | t | ) | [inline] |
Change brace and parenthesis match highlighting time, in nanoseconds.
A match highlight time of 0 disables brace matching.
| void FX::FXText::setHiliteStyles | ( | FXHiliteStyle * | styles | ) |
Set highlight styles.
The table of styles is only referenced by the widget; it is not copied. Thus, multiple widgets may share a common style table. Some care must be taken to populate the style-buffer only with numbers inside the style table.
| void FX::FXText::setVisibleColumns | ( | FXint | cols | ) |
Change number of visible columns.
The number of visible columns is used to calculate the default height the text widget reports to its parent layout manager.
| void FX::FXText::setVisibleRows | ( | FXint | rows | ) |
Change number of visible rows.
The number of visible rows is used to calculate the default height the text widget reports to its parent layout manager.
