A text label.
Its position is defined by the member position and the setting of setPositionAlignment. The latter controls which part of the text rect shall be aligned with position.
The text alignment itself (i.e. left, center, right) can be controlled with setTextAlignment.
The text may be rotated around the position point with setRotation.

Creates a text item and sets default values.
The created item is automatically registered with parentPlot. This QCustomPlot instance takes ownership of the item, so do not delete it manually but use QCustomPlot::removeItem() instead.

This function is used to decide whether a click hits a layerable object or not.
pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the shortest pixel distance of this point to the object. If the object is either invisible or the distance couldn't be determined, -1.0 is returned. Further, if onlySelectable is true and the object is not selectable, -1.0 is returned, too.
If the object is represented not by single lines but by an area like a QCPItemText or the bars of a QCPBars plottable, a click inside the area should also be considered a hit. In these cases this function thus returns a constant value greater zero but still below the parent plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).
Providing a constant value for area objects allows selecting line objects even when they are obscured by such area objects, by clicking close to the lines (i.e. closer than 0.99*selectionTolerance).
The actual setting of the selection state is not done by this function. This is handled by the parent QCustomPlot when the mouseReleaseEvent occurs, and the finally selected object is notified via the selectEvent/ deselectEvent methods.
details is an optional output parameter. Every layerable subclass may place any information in details. This information will be passed to selectEvent when the parent QCustomPlot decides on the basis of this selectTest call, that the object was successfully selected. The subsequent call to selectEvent will carry the details. This is useful for multi-part objects (like QCPAxis). This way, a possibly complex calculation to decide which part was clicked is only done once in selectTest. The result (i.e. the actually clicked part) can then be placed in details. So in the subsequent selectEvent, the decision which part was selected doesn't have to be done a second time for a single selection operation.
In the case of 1D Plottables (QCPAbstractPlottable1D, like QCPGraph or QCPBars) details will be set to a QCPDataSelection, describing the closest data point to pos.
You may pass 0 as details to indicate that you are not interested in those selection details.

void QCPItemText::setPadding | ( | const QMargins & | padding | ) |
Sets the distance between the border of the text rectangle and the text. The appearance (and visibility) of the text rectangle can be controlled with setPen and setBrush.

void QCPItemText::setPen | ( | const QPen & | pen | ) |
Sets the pen that will be used do draw a rectangular border around the text. To disable the border, set pen to Qt::NoPen.

void QCPItemText::setPositionAlignment | ( | Qt::Alignment | alignment | ) |
Sets which point of the text rect shall be aligned with position.
Examples:
Qt::AlignHCenter | Qt::AlignTop
, the text will be positioned such that the top of the text rect will be horizontally centered on position. Qt::AlignLeft | Qt::AlignBottom
, position will indicate the bottom left corner of the text rect.If you want to control the alignment of (multi-lined) text within the text rect, use setTextAlignment.

void QCPItemText::setRotation | ( | double | degrees | ) |
Sets the angle in degrees by which the text (and the text rectangle, if visible) will be rotated around position.

void QCPItemText::setText | ( | const QString & | text | ) |
Sets the text that will be displayed. Multi-line texts are supported by inserting a line break character, e.g. '

void QCPItemText::setTextAlignment | ( | Qt::Alignment | alignment | ) |
Controls how (multi-lined) text is aligned inside the text rect (typically Qt::AlignLeft, Qt::AlignCenter or Qt::AlignRight).
