From f75cf62d2f36a66fcdc7be7161a3798bea926509 Mon Sep 17 00:00:00 2001 From: ocornut Date: Wed, 4 Sep 2024 15:31:39 +0200 Subject: [PATCH] Tables: fixed resizing columns when using multiple synched instances that are layed out at different X positions. (#7933) TableGetMaxColumnWidth() was using MinX from previous column. Storing info in column. Still incorrect interleaved data for multi-instances but it covers majority of use cases. --- docs/CHANGELOG.txt | 4 ++-- imgui_internal.h | 3 ++- imgui_tables.cpp | 10 +++++----- 3 files changed, 9 insertions(+), 8 deletions(-) diff --git a/docs/CHANGELOG.txt b/docs/CHANGELOG.txt index 95745581a..4c2537a8c 100644 --- a/docs/CHANGELOG.txt +++ b/docs/CHANGELOG.txt @@ -85,8 +85,8 @@ Other changes: - Tables: fixes/revert a 1.90 change were outer border would be moved bottom and right by an extra pixel + rework the change so that contents doesn't overlap the bottom and right border in a scrolling table.
