From 082b20e46b21308c7f00816f1d46065d315861ee Mon Sep 17 00:00:00 2001 From: ocornut Date: Fri, 10 Feb 2023 15:59:01 +0100 Subject: [PATCH] Internals: Settings: added ClearWindowSettings(). Extract part of CreateNewWindow() into InitOrLoadWindowSettings(). Designed to that if the window reappear in the session it won't take an additional slot. --- imgui.cpp | 70 +++++++++++++++++++++++++++++++++--------------- imgui_internal.h | 2 ++ 2 files changed, 51 insertions(+), 21 deletions(-) diff --git a/imgui.cpp b/imgui.cpp index 073f12f94..fc7e963ea 100644 --- a/imgui.cpp +++ b/imgui.cpp @@ -3631,7 +3631,7 @@ ImGuiWindow::ImGuiWindow(ImGuiContext* context, const char* name) : DrawListInst ScrollTargetCenterRatio = ImVec2(0.5f, 0.5f); AutoFitFramesX = AutoFitFramesY = -1; AutoPosLastDirection = ImGuiDir_None; - SetWindowPosAllowFlags = SetWindowSizeAllowFlags = SetWindowCollapsedAllowFlags = ImGuiCond_Always | ImGuiCond_Once | ImGuiCond_FirstUseEver | ImGuiCond_Appearing; + SetWindowPosAllowFlags = SetWindowSizeAllowFlags = SetWindowCollapsedAllowFlags = 0; SetWindowPosVal = SetWindowPosPivot = ImVec2(FLT_MAX, FLT_MAX); LastFrameActive = -1; LastTimeActive = -1.0f; @@ -5360,32 +5360,22 @@ static void UpdateWindowInFocusOrderList(ImGuiWindow* window, bool just_created, window->IsExplicitChild = new_is_explicit_child; } -static ImGuiWindow* CreateNewWindow(const char* name, ImGuiWindowFlags flags) +static void InitOrLoadWindowSettings(ImGuiWindow* window, ImGuiWindowSettings* settings) { - ImGuiContext& g = *GImGui; - //IMGUI_DEBUG_LOG("CreateNewWindow '%s', flags = 0x%08X\n", name, flags); - - // Create window the first time - ImGuiWindow* window = IM_NEW(ImGuiWindow)(&g, name); - window->Flags = flags; - g.WindowsById.SetVoidPtr(window->ID, window); - - // Default/arbitrary window position.
