| Summary | 0019843: GTK2 scrollbar - top wraps to bottom - (SynMemo scrolling weirdness) | ||||||||
| Description | When in a SynMemo you pull the track-thumb to topmost (vert. scrollbar) or leftmost (hor. scrollbar), then the SynMemo scrolls to resp. eond of file or past eol. | ||||||||
| Steps To Reproduce | See SourceEditor of Lazarus. Open a sourcefile. Place cursor at begin of file. Grab scroll-thumb on horizontal scrollbar and move it to the left: text disappears, gutter is still there as are code-folding indicators. Grab scroll-thumb oon vertical scrollbar and move to top: last lines of the file will appear. This issue does not occur when you click the arrows of the scrollbar. It looks like we assing some negative value to the scrolling mechanism when it should be zero? | ||||||||
| Additional Information | The described behaviour does not happen to a TMemo, so it seems SynEdit related. | ||||||||
| Tags | No tags attached. | ||||||||

Does not happen in Windows (win9x) (same Lazarus revision), so might be a widgetset problem. |

- How many lines does the file in the editor have? - Do you have "scroll past end of file" enabled? - Do you have "always show caret" enabled? (Best attach your editor options)? Was it recently introduced? Do you know the revision? Or has it been there longer? |

> - How many lines does the file in the editor have? Any file "bigger than the window" will do. > - Do you have "scroll past end of file" enabled? No > - Do you have "always show caret" enabled? Closest thing is "Always visible cursor", it it disabled Testing with a TSynMemo reveals tha the horizontal issue disappears when eoScrollPastEol is set to False. > (Best attach your editor options)? I'll attach my editor options. It however does not seem to be a TSynMemo issue, I get the exact same behaviour with the OI (vert. scrolling to topmost goes to bottom instead), and with a TTreeView (hor. and vert). > Was it recently introduced? Do you know the revision? Or has it been there longer? It seems recent to me. My previous rev was about 200 before my current, and I don't remeber it being there. |

Definitely Widgetset then. SynEdit does some handling of the scrollbar, but OI points to the scrollbar itself. Doesn't happen on all GTK2, tested with older fedora => all ok It may be worth adding your gtk2 version. Since it's OI too, I changed the Issue title |

The related issue was solved with a patch. Does it solve this one, too? |

Fixed in the mean time. |
