So you do not always realize that you are really just dragging the nearest movable point. The point being dragged does not jump under the pointer either but remains at a constant xy offset from the pointer while dragging it.

When the text is selected by clicking on it, a white outline is drawn around it. * This outline then persists whenever the text is click-dragged thereafter. * However if the text is click-dragged (without first clicking on it) the white outline is not drawn around it. * The white outline should also be drawn around the text when the pointer moves over it. * Other elements highlight when the pointer moves over them and remain highlighted when click-dragged without first having to be clicked. 6) Ctrl-drag does not include text elements * Create a couple of text (not docked to the points or view edges) and point elements * Use Ctrl-A keystroke to select all * Observe that click-drag on one of the points with Ctrl key held down only simultaneously moves the points. * The click-drag on one of the texts with Ctrl key held down moves only that particular text. 7) The documentation for the re-positioning of the label of a point, line or segment is a bit sketchy (see "Moving elements"). * Click "Move Element", hold down the shift key and drag the label of a point or line. * Observe the dim white line that appears while dragging the label (not mentioned in the documentation). * The label for a point can be positioned at a fixed (x,y) pixel offset from the point (maximum radius of 72 pixels). * The label for a line or segment can only be moved to either end or side of the line or segment (not mentioned in the documentation). * For the segment labels the position is a percentage of the distance between the endpoints (not mentioned in the documentation). ~~#0000CC:Observed using Version: 2.9 build 1783 (2015/08/03 18:17)~~ Best regards, Alexander Elkins ]]> aelkins Thu, 17 Sep 2015 18:30:24 +0100 http://cinderella-geometry.com/tiki-view_forum_thread.php?forumId=1&comments_parentId=1030 singerarts.com Mon, 01 Jun 2015 12:05:50 +0100 http://cinderella-geometry.com/tiki-view_forum_thread.php?forumId=1&comments_parentId=1027 DorettePronk Tue, 24 Feb 2015 21:40:35 +0100
