Detailed Description

An IlvCodeEditor specialization providing features to create a debugger-like text control.

Library: ilvadvgdt

The text has a margin area where markers can be displayed. This can indicate a breakpoint or the current selected line.

Member Function Documentation

IlBoolean IlvDebuggerEditor::setErrorLine ( IlInt  line)

Registers the given line as a line with an error.

The line is memorized as erroneous, colorized with the defined color, and the error symbol is added to its margin.

Parameters
linethe line to set as erroneous.
Returns
IlTrue if the line is valid and a specific error symbol existed; otherwise returns IlFalse.
Note
This function does not follow the convention that line numbering starts at 1.
IlBoolean IlvDebuggerEditor::setErrorLocation ( IlInt  beginLine,
IlInt  beginColumn,
IlInt  endLine,
IlInt  endColumn 
)

Registers the given text span as being in error.

Parameters
beginLinethe start line of the text span.
beginColumnthe start column of the text span.
endLinethe final line of the text span.
endColumnthe final column of the text span.
Returns
IlFalse if beginLine or endLine are invalid or no specific error symbol exists; otherwise returns IlTrue.

The lines are memorized as erroneous, colorized with the defined color, and the error symbol is added to their margins. In case beginColumn or endColumn indicate that their respective lines are only partially in error, the start and end columns are memorized.

Note
This function does not follow the convention that line numbering starts at 1.
IlBoolean IlvDebuggerEditor::unsetAllErrorLines ( )

Removes all error marks from the editor.

Returns
always IlTrue.

For all error memorized lines, the error symbols are cleared form their margin and the decoration are recomputed. Finally the whole editor is redrawn.

Note
This function does not follow the convention that line numbering starts at 1.
