Show axes coordinates in Qt figures (bug #44959) * Canvas.h: new private bool member m_updtaCurrentPoint, to decide wether update the figure "currentpoint" property * Canvas.h (Canvas::enableCurrentPointUpdates): new method to set m_updtaCurrentPoint * Canvas.cc (Canvas::canvasMousePressEvent): move the code for axes/object selection in a dedicated method and call this method (select_object) instead. * Canvas.cc (Canvas::select_object): new method for axes/object selection. * Canvas.cc (Canvas::canvasMouseMoveEvent): update the parent figure status bar with the hovered axes coordinates * Figure.h: declare new method updateStatusBar * Figure.h: declare new private QStatusBar member m_statusBar. Include QStatusBar.h * Figure.cc (Figure::Figure): unconditionally enable mouse traching * Figure.cc (Figure::Figure): add status below of the canvas * Figure.cc (Figure::update): take status bar into account when updating the figure position * Figure.cc (Figure::update): remove some of the leftover debug comments * Figure.cc: define new method updateStatusBar
