From 82ba2056462310b103ad16fba726340886e5b0b7 Mon Sep 17 00:00:00 2001 From: Julian Eisel Date: Tue, 8 Nov 2022 12:14:31 +0100 Subject: Fix T85870: ColorRamp Keyframes crash Blender The color-band needs to do some special, rather awkward updating of the UI state when certain values are changed. As @lichtwerk noted in the report, this was done to the wrong buttons. Now lookup the proper buttons, and don't assume that `uiItemR()` only adds a single button (which often isn't the case). --- .../editors/interface/interface_templates.c | 27 +++++++++++++++------- 1 file changed, 19 insertions(+), 8 deletions(-) diff --git a/source/blender/editors/interface/interface_templates.c b/source/blender/editors/interface/interface_templates.c index a3259831c9f..b32aa82ad9e 100644 --- a/source/blender/editors/interface/interface_templates.c +++ b/source/blender/editors/interface/interface_templates.c @@ -3673,13 +3673,9 @@ static void colorband_buttons_layout(uiLayout *layout, row = uiLayoutRow(split, false); uiItemR(row, &ptr, "position", 0, IFACE_("Pos"), ICON_NONE); - bt = block->buttons.last; - UI_but_func_set(bt, colorband_update_cb, bt, coba); row = uiLayoutRow(layout, false); uiItemR(row, &ptr, "color", 0, "", ICON_NONE); - bt = block->buttons.last; - UI_but_funcN_set(bt, rna_update_cb, MEM_dupallocN(cb), NULL); } else { split = uiLayoutSplit(layout, 0.5f, false); @@ -3704,13 +3700,28 @@ static void colorband_buttons_layout(uiLayout *layout, row = uiLayoutRow(subsplit, false); uiItemR(row, &ptr, "position", UI_ITEM_R_SLIDER, IFACE_("Pos"), ICON_NONE); - bt = block->buttons.last; - UI_but_func_set(bt, colorband_update_cb, bt, coba); row = uiLayoutRow(split, false); uiItemR(row, &ptr, "color", 0, "", ICON_NONE); - bt = block->buttons.last; - UI_but_funcN_set(bt, rna_update_cb, MEM_dupallocN(cb), NULL); + } + + /* Some special (rather awkward) treatment to update UI state on certain property changes. */ + LISTBASE_FOREACH_BACKWARD (uiBut *, but, &block->buttons) { + if (but->rnapoin.data != ptr.data) { + continue; + } + if (!but->rnaprop) { + continue; + } + + const char *prop_identifier = RNA_property_identifier(but->rnaprop); + if (STREQ(prop_identifier, "position")) { + UI_but_func_set(but, colorband_update_cb, but, coba); + } + + if (STREQ(prop_identifier, "color")) { + UI_but_funcN_set(but, rna_update_cb, MEM_dupallocN(cb), NULL); + } } } } -- cgit v1.2.3
