Detailed Description

The QextScintillaBase class implements the Scintilla editor widget and its low-level API.

Scintilla (http://www.scintilla.org) is a powerful C++ editor class that supports many features including syntax styling, error indicators, code completion and call tips. It is particularly useful as a programmer's editor.

QextScintillaBase is a port to TQt of Scintilla. It implements the standard Scintilla API which consists of a number of messages each taking up to two arguments.

See QextScintilla for the implementation of a higher level API that is more consistent with the rest of the TQt toolkit.

Member Enumeration Documentation

anonymous enum

The low-level Scintilla API is implemented as a set of messages each of which takes up to two parameters (wParam and lParam) and optionally return a value. This enum defines all the possible messages.

See also:
SendScintilla()
Enumerator:
SCI_ADDTEXT  This message appends some text to the end of the document. wParam is the length of the text. lParam is the text to be appended.
SCI_GETCURRENTPOS  This message returns the current position.

See also:
SCI_SETCURRENTPOS
SCI_GETANCHOR  This message returns the anchor.

See also:
SCI_SETANCHOR
SCI_SETSAVEPOINT  This message marks the current state of the text as the the save point. This is usually done when the text is saved or loaded.

See also:
SCN_SAVEPOINTREACHED(), SCN_SAVEPOINTLEFT()
SCI_MARKERLINEFROMHANDLE  This message returns the line that contains a particular instance of a marker. wParam is the handle of the marker.

See also:
SCI_MARKERADD
SCI_MARKERDELETEHANDLE  This message removes a particular instance of a marker. wParam is the handle of the marker.

See also:
SCI_MARKERADD
SCI_GOTOPOS  This message clears the current selection and sets the current position. wParam is the new current position.

See also:

SCI_GETENDSTYLED  This message returns the character position of the start of the text that needs to be syntax styled.

See also:
SCN_STYLENEEDED()
SCI_MARKERDEFINE  This message sets the symbol used to draw one of 32 markers. Some markers have pre-defined uses, see the SC_MARKNUM_* values. wParam is the number of the marker. lParam is the marker symbol and is one of the SC_MARK_* values.

See also:
SCI_MARKERADD, SCI_MARKERDEFINEPIXMAP
SCI_MARKERSETFORE  This message sets the foreground colour used to draw a marker. A colour is represented as a 24 bit value. The 8 least significant bits correspond to red, the middle 8 bits correspond to green, and the 8 most significant bits correspond to blue. The default value is 0x000000. wParam is the number of the marker. lParam is the colour.

See also:
SCI_MARKERSETBACK
SCI_MARKERSETBACK  This message sets the background colour used to draw a marker. A colour is represented as a 24 bit value. The 8 least significant bits correspond to red, the middle 8 bits correspond to green, and the 8 most significant bits correspond to blue. The default value is 0xffffff. wParam is the number of the marker. lParam is the colour.

See also:
SCI_MARKERSETFORE
SCI_MARKERADD  This message adds a marker to a line. A handle for the marker is returned which can be used to track the marker's position. wParam is the line number. lParam is the number of the marker.

Member Function Documentation

static QextScintillaBase* QextScintillaBase::pool (  )  [static]

Returns the viewport widget. This is the widget that actually contains the text.

void QextScintillaBase::TQSCN_SELCHANGED ( bool  yes  )  [signal]

This signal is emitted when text is selected or de-selected. yes is TRUE if text has been selected and FALSE if text has been deselected.

void QextScintillaBase::SCN_AUTOCSELECTION ( const char *  selection,

) [signal]

This signal is emitted when the user selects an item in an auto-completion list. It is emitted before the selection is inserted. The insertion can be cancelled by sending an SCI_AUTOCANCEL message from a connected slot. position is the start position of the word being completed. selection is the text of the selection.

void QextScintillaBase::SCEN_CHANGE (  )  [signal]

This signal is emitted when the document has changed for any reason.

void QextScintillaBase::SCN_CALLTIPCLICK ( int  direction  )  [signal]

This signal ir emitted when the user clicks on a calltip. position is 1 if the user clicked on the up arrow, 2 if the user clicked on the down arrow, and 0 if the user clicked elsewhere.

void QextScintillaBase::SCN_CHARADDED ( int  charadded  )  [signal]

This signal is emitted whenever the user enters an ordinary character into the text. charadded is the character. It can be used to decide to display a call tip or an auto-completion list.

int  modifiers 
) [signal]

This signal is emitted when the user clicks on text in a style with the hotspot attribute set. position is the position in the text where the click occured. modifiers is the logical or of the modifier keys that were pressed when the user clicked.

void QextScintillaBase::SCN_HOTSPOTDOUBLECLICK ( int  position,

unsigned  long,
long   
) [signal]

This signal is emitted when a recordable editor command has been executed.

void QextScintillaBase::SCN_MARGINCLICK ( int  position,
int  modifiers,
int  margin 
) [signal]

This signal is emitted when the user clicks on a sensitive margin. position is the position of the start of the line against which the user clicked. modifiers is the logical or of the modifier keys that were pressed when the user clicked. margin is the number of the margin the user clicked in: 0, 1 or 2.
