LogView: A scrollable (output-only) text to display a growing log, very much like the "tail -f" shell command.
Definition at line 37 of file YLogView.h.
|
protected |
Constructor.
'label' is the caption above the log. 'visibleLines' indicates how many lines should be visible by default (unless changed by other layout constraints), 'maxLines' specifies how many lines (always the last ones) to keep in the log. 0 for 'maxLines' means "keep all lines".
Definition at line 58 of file YLogView.cc.
|
virtual |
Destructor.
Definition at line 69 of file YLogView.cc.
void YLogView::appendLines | ( | const std::string & | text | ) |
Append one or more lines to the log text and trigger a display update.
Definition at line 161 of file YLogView.cc.
void YLogView::clearText | ( | ) |
Clear the log text and trigger a display update.
Definition at line 206 of file YLogView.cc.
|
protectedpure virtual |
Display the part of the log text that should be displayed. 'text' contains the last 'visibleLines()' lines. This is called whenever the log text changes. Note that the text might also be empty, in which case the displayed log text should be cleared.
Derived classes are required to implement this.

virtual |
Get a property. Reimplemented from YWidget.
This method may throw YUIPropertyExceptions.
Reimplemented from YWidget.
Definition at line 273 of file YLogView.cc.
std::string YLogView::label | ( | ) | const |
Return the label (the caption above the log text).
Definition at line 76 of file YLogView.cc.
std::string YLogView::lastLine | ( | ) | const |
Return the last log line.
Definition at line 151 of file YLogView.cc.
int YLogView::lines | ( | ) | const |
Return the current number of lines.
Definition at line 213 of file YLogView.cc.
std::string YLogView::logText | ( | ) | const |
Return the entire log text as one large string of concatenated lines delimited with newlines.
Definition at line 125 of file YLogView.cc.
int YLogView::maxLines | ( | ) | const |
Return the maximum number of lines to store. The last maxLines() lines of the log text will be kept.
Definition at line 104 of file YLogView.cc.
|
virtual |
Return this class's property set. This also initializes the property upon the first call.

virtual |
Set the label (the caption above the log text).
Derived classes are free to reimplement this, but they should call this base class method at the end of the overloaded function.
Definition at line 83 of file YLogView.cc.
|
inline |
Set (replace) the entire log text and trigger a display update.
Definition at line 122 of file YLogView.h.
void YLogView::setMaxLines | ( | int | newMaxLines | ) |
Set the maximum number of lines to store. "0" means "keep all lines" (beware of memory overflow!).
If the new value is lower than the old value, any (now) excess lines before the last 'newMaxLines' lines of the log text is cut off and a display update is triggered.
This method is intentionally not virtual since a display update is triggered when appropriate.
Definition at line 111 of file YLogView.cc.
|
virtual |
Set a property. Reimplemented from YWidget.
This function may throw YUIPropertyExceptions.
This function returns 'true' if the value was successfully set and 'false' if that value requires special handling (not in error cases: those are covered by exceptions).
Reimplemented from YWidget.
Definition at line 254 of file YLogView.cc.

inlinevirtual |
Set the string of this widget that holds the keyboard shortcut.

Definition at line 186 of file YLogView.h.
void YLogView::setVisibleLines | ( | int | newVisibleLines | ) |
Set the number of visible lines. Changing this has only effect upon the next geometry call, so applications calling this function might want to trigger a re-layout afterwards.
This method is intentionally not virtual: visibleLines() should be queried in the preferredHeight() implementation.
Definition at line 97 of file YLogView.cc.

Returns a descriptive name of this widget class for logging, debugging etc.
