Copy a Box.
Reimplemented from TObject.
Reimplemented in TPave, TPaletteAxis, TLegend, TWbox, TPaveLabel, and TFrame.
Compute distance from point px,py to a box.
Compute the closest distance of approach from point px,py to the edges of this box. The distance is computed in pixels units.
In case of a filled box the distance returned is 0 if the point (px,py) is inside the box, and is huge if the point is outside.
Reimplemented from TObject.
Reimplemented in TPaletteAxis, TPave, and TDiamond.
Draw this box with its current attributes.
if the box has no fill style (ie fill style=0), the box contour is drawn if the box has a fill style, the box contour is not drawn by default. to force the contour to be drawn, specify option "l"
Reimplemented from TObject.
Reimplemented in TPave, TPaveText, TLegend, TWbox, TPaveLabel, TDiamond, TPavesText, and TFrame.
Execute action corresponding to one event.
This member function is called when a BOX/WBOX/PAD object is clicked.
If the mouse is clicked in one of the 4 corners of the box (pA,pB,pC,pD) the box is resized with the rubber rectangle.
If the mouse is clicked inside the box, the box is moved.
If the mouse is clicked on the 4 edges (pL,pR,pTop,pBot), the box is rescaled parallel to this edge (same as Motif window manager).
Note that this function is duplicated on purpose by TPad::ExecuteEvent. If somebody modifies this function, may be similar changes should also be applied to TPad::ExecuteEvent.
Reimplemented from TObject.
