From fa4e79dc862e10ff97f5a51d6c0241a3d1224bb5 Mon Sep 17 00:00:00 2001 From: LuChiChick <1084116302@qq.com> Date: Fri, 24 Apr 2026 17:07:07 +0800 Subject: [PATCH] Implemented the copy, paste, and cut functions in the workspace, with corresponding shortcut key responses. The clipboard functionality is implemented internally and does not interact with the operating system for now. --- Inc/Workflow_Editor.hpp | 10 ++ Src/Workflow_Editor.cpp | 346 +++++++++++++++++++++++++--------------- 2 files changed, 228 insertions(+), 128 deletions(-) diff --git a/Inc/Workflow_Editor.hpp b/Inc/Workflow_Editor.hpp index ad09ace..767416d 100644 --- a/Inc/Workflow_Editor.hpp +++ b/Inc/Workflow_Editor.hpp @@ -7,6 +7,7 @@ #include "imnodes.h" #include "ID_Generator.hpp" #include "Nodes_And_Connectors.hpp" +#include "Json_Utilities.hpp" // 节点编辑器类 class Workflow_Editor @@ -29,6 +30,9 @@ protected: std::vector> Node_Pool;
