From ac7b82d7c1fbd8bfd38e117faa581b3a65d98d87 Mon Sep 17 00:00:00 2001 From: whitequark Date: Thu, 23 May 2019 17:19:37 +0000 Subject: [PATCH] Allow configuring the amount of digits displayed after decimal point. This is useful in niche cases, like making angular measurement tools. Also, use simpler and more principled code for numeric precision while editing constraints: don't special-case angles, but use up to 10 digits after the decimal point for everything. --- src/confscreen.cpp | 25 ++++++++++++++++++++++--- src/drawconstraint.cpp | 6 +----- src/mouse.cpp | 40 +++++++++++++++++----------------------- src/solvespace.cpp | 9 +++++++++ src/solvespace.h | 2 ++ src/ui.h | 18 ++++++++++-------- 6 files changed, 61 insertions(+), 39 deletions(-) diff --git a/src/confscreen.cpp b/src/confscreen.cpp index df5a95d..12b5437 100644 --- a/src/confscreen.cpp +++ b/src/confscreen.cpp @@ -60,10 +60,15 @@ void TextWindow::ScreenChangeGridSpacing(int link, uint32_t v) { } void TextWindow::ScreenChangeDigitsAfterDecimal(int link, uint32_t v) { - SS.TW.ShowEditControl(3, ssprintf("%d", SS.UnitDigitsAfterDecimal()));
