| Summary | 0002110: Selection bug in JvEditor | ||||
| Description | Compile project attached in _JvHlEditorTest.zip (containing one form wit JvEditor window) and run it. Then mouse-click 'x' character inside the first line of JvEditor window. Then Press Ctrl-End (cared should move to the end of the text) and then press Crtl+{Left arrow}. Instead of one character selection a big block of text starting from mouse-clicked character up to current caret position will be selected. | ||||
| Additional Information | Unfortunatelly this bug is not always reproducible, try to repeat the described sequence of mouse click + keypressings several times. | ||||

This bug is always reproducible under the next circumstances: 1) Left-mouse-button-click somewhere inside first row of the text in (near 'x' char in _JvHlEditorTest.zip example), then, holding mouse button down (do not release it!), move mouse in any direction to select a small piece of text, then (continue holding button down!) return mouse pointer to the click position (to remove selection) then release mouse button. Then press CTRL+END to move caret to the end of the text and then press Shift+{LeftArrow}. Wrong piece of text will be selected. It seems that something is wrong in TJvCustomEditorBase.MouseMove near SetSel(MouseMoveXX, MouseMoveYY) call but I cannot find what exacltly wrong, sorry. |

The mouse related code was easy to fix. I just added a FSelection.Selecting := False in MouseUp. But for the keyboard it complicated because I do not want to add the code to every key. |

Fixed in CVS. The MouseUp fix had introduces another bug. So I have removed it. The keyboard fix I found (set FSelection.Selecting := False in KeyDown when no Shift-Key is pressed) fixed the whole bug. The mouse issue was just a result of the keyboard issue. |
