// Think again! It is the most useful reference code that you and other coders will want to refer to and call.
// Have the ImGui::ShowDemoWindow() function wired in an always-available debug menu of your game/app!
// Also include Metrics! ItemPicker! DebugLog! and other debug features.
// Removing this file from your project is hindering access to documentation for everyone in your team,
// likely leading you to poorer usage of the library.

// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().
// If you want to link core Dear ImGui in your shipped builds but want a thorough guarantee that the demo will not be
// linked, you can setup your imconfig.h with #define IMGUI_DISABLE_DEMO_WINDOWS and those functions will be empty.
// In another situation, whenever you have Dear ImGui available you probably want this to be available for reference.
// Thank you,
// -Your beloved friend, imgui_demo.cpp (which you won't delete)
// Message to beginner C/C++ programmers about the meaning of the 'static' keyword:
// In this demo code, we frequently use 'static' variables inside functions. A static variable persists across calls,
// so it is essentially like a global variable but declared inside the scope of the function. We do this as a way to
// gather code and data in the same place, to make the demo source code faster to read, faster to write, and smaller
// in size. It also happens to be a convenient way of storing simple UI related information as long as your function
// doesn't need to be reentrant or used in multiple threads. This might be a pattern you will want to use in your code,
// but most of the real data you would be editing is likely going to be stored outside your functions.
// The Demo code in this file is designed to be easy to copy-and-paste into your application!
// Because of this:
// - We never omit the ImGui:: prefix when calling functions, even though most code here is in the same namespace.
// - We try to declare static variables in the local scope, as close as possible to the code using them.
// - We never use any of the helpers/facilities used internally by Dear ImGui, unless available in the public API.
// - We never use maths operators on ImVec2/ImVec4. For our other sources files we use them, and they are provided

2022-05-18 16:23:10 -04:00
// and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h.
// Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp.

// In practice, if you frequently use a given type that is not covered by the normal API entry points,
// you can wrap it yourself inside a 1 line function which can take typed argument as value instead of void*,
// and then pass their address to the generic function. For example:
// bool MySliderU64(const char *label, u64* value, u64 min = 0, u64 max = 0, const char* format = "%lld")
// {
// return SliderScalar(label, ImGuiDataType_U64, value, &min, &max, format);
// }
// Setup limits (as helper variables so we can take their address, as explained above)
// Note: SliderScalar() functions have a maximum usable range of half the natural type maximum, hence the /2.

// "seek" to display only items in the visible area.
// To use the clipper we can replace your standard loop:
// for (int i = 0; i < Items.Size; i++)

// ImGuiListClipper clipper;

// without processing all the ones before)

// We would need random-access on the post-filtered list.
// A typical application wanting coarse clipping and filtering may want to pre-compute an array of indices
// or offsets of items that passed the filtering test, recomputing this array when user changes the filter,
// and appending newly elements as they are inserted. This is left as a task to the user until we can manage
// to improve this example code!

//-----------------------------------------------------------------------------
// Demonstrate using DockSpace() to create an explicit docking node within an existing window.
// Note: You can use most Docking facilities without calling any API. You DO NOT need to call DockSpace() to use Docking!
// - Drag from window title bar or their tab to dock/undock. Hold SHIFT to disable docking.
// - Drag from window menu button (upper-left button) to undock an entire node (all windows).
// - When io.ConfigDockingWithShift == true, you instead need to hold SHIFT to _enable_ docking/undocking.
// About dockspaces:
// - Use DockSpace() to create an explicit dock node _within_ an existing window.
// - Use DockSpaceOverViewport() to create an explicit dock node covering the screen or a specific viewport.
// This is often used with ImGuiDockNodeFlags_PassthruCentralNode.
// - Important: Dockspaces need to be submitted _before_ any window they can host. Submit it early in your frame! (*)
// - Important: Dockspaces need to be kept alive if hidden, otherwise windows docked into it will be undocked.
// e.g. if you have multiple tabs with a dockspace inside each tab: submit the non-visible dockspaces with ImGuiDockNodeFlags_KeepAliveOnly.
// (*) because of this constraint, the implicit \"Debug\" window can not be docked into an explicit DockSpace() node,
// because that window is submitted as part of the part of the NewFrame() call. An easy workaround is that you can create
// your own implicit "Debug##2" window after calling DockSpace() and leave it in the window stack for anyone to use.

update ImGui to 1.89.8 commit f8704cd085c4347f835c21dc12a3951924143872 with Furnace patches

// In most cases you should be able to just call DockSpaceOverViewport() and ignore all the code below!
// In this specific demo, we are not using DockSpaceOverViewport() because:
// - (1) we allow the host window to be floating/moveable instead of filling the viewport (when opt_fullscreen == false)
// - (2) we allow the host window to have padding (when opt_padding == true)
// - (3) we expose many flags and need a way to have them visible.
// - (4) we have a local menu bar in the host window (vs. you could use BeginMainMenuBar() + DockSpaceOverViewport()
// in your code, but we don't here because we allow the window to be floating)
de-submodule ImGui allows for local modification which is necessary see #442
