All of these widgets require you to predefine an :class:`matplotlib.axes.Axes` instance and pass that as the first arg. matplotlib doesn't try to be too smart with respect to layout -- you will have to figure out how wide and tall you want your Axes to be to accommodate your widget. i(tprint_functionN(tdist(tCirclet Rectangle(tLine2D(tblended_transform_factorytLockDrawcBsDeZdZdZdZdZdZdZdZRS(sY Some widgets, like the cursor, draw onto the canvas, and this is not desirable under all circumstances, like when the toolbar is in zoom-to-rect mode and drawing a rectangle.

If 'pixels', they are in pixels. *button* is a list of integers indicating which mouse buttons should be used for rectangle selection. You can also specify a single integer if only a single button is desired. Default is *None*, which does not limit which button can be used. Note, typically: 1 = left mouse button 2 = center mouse button (scroll wheel) 3 = right mouse button R0R.R/RtnoneRRRttwhitet edgecolortblackRg?tfilliiRR?t linestylet-RoiRtpixelsN(ii(sdataR(%RR RRR$RRRRRRtto_drawRR;RRRRR~RRRRRRRtminspanxtminspanyt isinstancetlistt validButtonstintRt spancoordstdrawtypet eventpresst eventrelease( R RRR'R R!RRRR&Re((sL/opt/xtal/ccp4-6.5-linux32/lib/python2.7/site-packages/matplotlib/widgets.pyR sR.                   cCs+|jr'|jj|jj|_ndS(s!force an update of the backgroundN(RRRRRR(R R!((sL/opt/xtal/ccp4-6.5-linux32/lib/python2.7/site-packages/matplotlib/widgets.pyR>s cCsb|js tS|jjj|s&tS|jdk rN|j|jkrNtSn|jdkrm|j |j kS|j|jjkr=|j |j kr=|j j j j |j|jf\}}|j j\}}|j j\}}t||}t||}t||}t||}||_||_tS|j |j kpa|j|jjkS(s*return *True* if *event* should be ignoredN(RRRRR R$RReR(RCRRRRRRRRtmaxtminRgRR;(R R!RgRtx0tx1ty0ty1((sL/opt/xtal/ccp4-6.5-linux32/lib/python2.7/site-packages/matplotlib/widgets.pyR(Cs.
