LogWidget

Displays an un-scrollable log

It's content cannot be modified by user, like a MemoWidget with editing disabled, but automatically scrolls down as new lines are added, and it wraps long lines.

class LogWidget : QWidget {

bool updateEvent();

bool resizeEvent();

Color backgroundColor;

Color textColor;

this(uint maxLen);

~this();

void add(dstring item);

void add(string item);

void clear();

}

Constructors

this this(uint maxLen): constructor

From QWidget

_minWidth uint _minWidth;: minimum width

_maxHeight uint _maxHeight;: maximum height
viewportX uint viewportX [@property getter]
viewportY uint viewportY [@property getter]: viewport coordinates. (drawable area for widget)
viewportWidth uint viewportWidth [@property getter]
viewportHeight uint viewportHeight [@property getter]: viewport size. (drawable area for widget)
isWritable bool isWritable(uint x, uint y): If a coordinate is within writing area, and writing area actually exists
moveTo void moveTo(uint newX, uint newY): move seek for next write to terminal. can only write in between: (_viewX .. _viewX + _viewWidth, _viewY .. _viewX + _viewHeight)
write bool write(dchar c, Color fg, Color bg): writes a character on terminal
write uint write(dstring s, Color fg, Color bg): writes a (d)string to terminal. if it does not fit in one line, it is wrapped
fillLine uint fillLine(dchar c, Color fg, Color bg, uint max): fill current line with a character. max is ignored if max==0
searchAndActivateWidget bool searchAndActivateWidget(QWidget target): activate the passed widget if this is actually the correct widget
eventSubscribe void eventSubscribe(uint newSub): called by itself, to update events subscribed to
eventSubscribe void eventSubscribe(): called by children when they want to re-subscribe to events
requestCursorPos void requestCursorPos(int x, int y): to set cursor position on terminal. will only work if this is active widget. set x or y or both to negative to hide cursor
requestScrollX bool requestScrollX(uint x): called to request to scrollX
requestScrollY bool requestScrollY(uint y): called to request to scrollY
initialize bool initialize(): Called after UI has been run
mouseEvent bool mouseEvent(MouseEvent mouse): Called when mouse is clicked with cursor on this widget.
keyboardEvent bool keyboardEvent(KeyboardEvent key, bool cycle): Called when key is pressed and this widget is active.
resizeEvent bool resizeEvent(): Called when widget size is changed, or widget should recalculate it's child widgets' sizes;
scrollEvent bool scrollEvent(): Called when the widget is rescrolled, but size not changed.
activateEvent bool activateEvent(bool isActive): called right after this widget is activated, or de-activated
timerEvent bool timerEvent(uint msecs): called often. msecs is the msecs since last timerEvent, not accurate
updateEvent bool updateEvent(): Called to update this widget
requestUpdate void requestUpdate(): To request parent to trigger an update event
requestResize void requestResize(): To request parent to trigger a resize event
onInitEvent InitFunction onInitEvent [@property setter]: use to change the custom initialize event
