In comparison, when doing the same from 26.0.90 (a recent build -- 4189d0e, 2017-10-29), the scrolling lags about 2 seconds behind (possibly another issue), and I cannot bring the scroller to the bottom of the window -- I only reach "98% L32461". Actually, the mouse pointer tracking seems to be off by some vertical pixel offset, such that if I click and drag the scroller, when the mouse pointer reaches halfway down the scroll bar, the scroller is not under it, but only 40% or 45% down. Other ways to scroll the text up (thus bringing the scroller down where it cannot be dragged), such as clicking in the area underneath the scroller, and clicking the scroll bar down arrow, work fine.

It caused scroll-bars to be over-drawn and the best working solution appears to be complete removal. (ns_set_horizontal_scroll_bar): Rewrite to handle horizontal scrollers correctly. (ns_set_vertical_scroll_bar): Set width to actual scroller width. (setFrame): Handle horizontal case. (dealloc): Handle horizontal case. (judge): Handle horizontal case. (setPosition): Rename pixel_height to pixel_length. (sendScrollEventAtLoc): Handle horizontal case. (mouseDown): Handle horizontal case and general tidy up of code. (mouseDragged): Handle horizontal case. Call sendScrollEventAtLoc with absolute pixel size instead of ratio. * src/window.h: Remove NS check. macOS 10.6 is probably a special case.

If so they might affect the offset. It has two buttons (up and down), at the bottom of the scrollbar. When I drag the scroller as far down as possible, the distance between the bottom of the scroller and the pointer (which should be zero) looks about the same as the total height of the two buttons, so I think you're right. > -- > Alan Third > From unknown Sun Jun 22 08:00:03 2025 X-Loop: help-debbugs@gnu.org Subject: bug#29053: 26.0.90: scroller cannot be dragged to bottom of window Resent-From: Alan Third Original-Sender: "Debbugs-submit" Resent-CC: bug-gnu-emacs@gnu.org Resent-Date: Thu, 02 Nov 2017 22:55:02 +0000 Resent-Message-ID: Resent-Sender: help-debbugs@gnu.org X-GNU-PR-Message: followup 29053 X-GNU-PR-Package: emacs X-GNU-PR-Keywords: To: "Charles A.

It was this. Emacs expects the scroller slot to be the same number of pixels as the whole scroller takes up. When there are buttons within the scroller area then the slot is smaller. On modern macOS versions because there are no buttons the use of a ratio looked silly, but when there are buttons (like on GNUstep too) then the ratio makes more sense. I shouldn’t have changed it. I’ve pushed a fix. It works on GNUstep, so I expect it will work for you too. -- Alan Third From unknown Sun Jun 22 08:00:03 2025 MIME-Version: 1.0 X-Mailer: MIME-tools 5.505 (Entity 5.505) X-Loop: help-debbugs@gnu.org From: help-debbugs@gnu.org (GNU bug Tracking System) To: charles@aurox.ch (Charles A.

Roelli) To: bug-gnu-emacs@gnu.org Subject: 26.0.90: scroller cannot be dragged to bottom of window X-detected-operating-system: by eggs.gnu.org: GNU/Linux 2.2.x-3.x [generic] [fuzzy] X-detected-operating-system: by eggs.gnu.org: GNU/Linux 2.6.x X-Received-From: 2001:4830:134:3::11 X-Spam-Score: -4.1 (----) X-Debbugs-Envelope-To: submit X-BeenThere: debbugs-submit@debbugs.gnu.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: debbugs-submit-bounces@debbugs.gnu.org Sender: "Debbugs-submit" X-Spam-Score: -4.1 (----) With 25.3 under macOS 10.6, from -q: C-x C-f src/xdisp.c RET I drag the vertical scroller from its top position (corresponding to the start of the buffer) down to its lowest (corresponding to end of buffer), and the mode line says "Bot L33113" and the last line of the buffer is shown. In comparison, when doing the same from 26.0.90 (a recent build -- 4189d0e, 2017-10-29), the scrolling lags about 2 seconds behind (possibly another issue), and I cannot bring the scroller to the bottom of the window -- I only reach "98% L32461". Actually, the mouse pointer tracking seems to be off by some vertical pixel offset, such that if I click and drag the scroller, when the mouse pointer reaches halfway down the scroll bar, the scroller is not under it, but only 40% or 45% down. Other ways to scroll the text up (thus bringing the scroller down where it cannot be dragged), such as clicking in the area underneath the scroller, and clicking the scroll bar down arrow, work fine. ------------=_1509789362-20724-1--
