Thank you for the quick answer and improvement. This works for me now.
from imgui.
Empty nodes are hidden and collapsed, unless they are the special CentralNode.
If you add the ImGuiDockNodeFlags_CentralNode
flag to DockBuilderAddNode()
it'll work:
ImGuiID dockspace_id = ImGui::GetID("MyDockNodeId");
static bool init = true;
ImVec2 mainSize = ImGui::GetMainViewport()->Size;
if (init)
{
init = false;
ImGui::DockBuilderRemoveNode(dockspace_id);
ImGui::DockBuilderAddNode(dockspace_id, ImGuiDockNodeFlags_CentralNode);
ImGui::DockBuilderSetNodeSize(dockspace_id, mainSize);
ImGuiID dock_id_left = 0, dock_id_right = 0;
ImGui::DockBuilderSplitNode(dockspace_id, ImGuiDir_Left, 0.25f, &dock_id_left, &dock_id_right);
ImGui::DockBuilderDockWindow("Window_1", dock_id_left);
ImGui::DockBuilderFinish(dockspace_id);
}
ImGui::Begin("Window_1");
ImGui::Text("Text 1");
ImGui::End();
However that this will create A FLOATING node and I am not sure this is what you want.
I think you want a DockSpace()
which is a node you are manually placing somewhere inside a window (very often in a screen-filling, non-moveable window):
const ImGuiViewport* viewport = ImGui::GetMainViewport();
ImGuiID dockspace_id = ImGui::GetID("MyDockNodeId");
if (ImGui::DockBuilderGetNode(dockspace_id) == NULL)
{
ImGui::DockBuilderRemoveNode(dockspace_id);
ImGui::DockBuilderAddNode(dockspace_id, ImGuiDockNodeFlags_DockSpace);
ImGui::DockBuilderSetNodeSize(dockspace_id, viewport->WorkSize);
ImGuiID dock_id_left = 0, dock_id_right = 0;
ImGui::DockBuilderSplitNode(dockspace_id, ImGuiDir_Left, 0.25f, &dock_id_left, &dock_id_right);
ImGui::DockBuilderDockWindow("Window_1", dock_id_left);
ImGui::DockBuilderFinish(dockspace_id);
}
// Create a window filling the screen, submit a dockspace inside
ImGui::SetNextWindowPos(viewport->WorkPos);
ImGui::SetNextWindowSize(viewport->WorkSize);
ImGui::SetNextWindowViewport(viewport->ID);
ImGui::PushStyleVar(ImGuiStyleVar_WindowRounding, 0.0f);
ImGui::PushStyleVar(ImGuiStyleVar_WindowBorderSize, 0.0f);
ImGui::PushStyleVar(ImGuiStyleVar_WindowPadding, ImVec2(0.0f, 0.0f));
ImGuiWindowFlags host_window_flags = ImGuiWindowFlags_NoDecoration | ImGuiWindowFlags_NoMove | ImGuiWindowFlags_NoDocking | ImGuiWindowFlags_NoBringToFrontOnFocus | ImGuiWindowFlags_NoNavFocus;
//host_window_flags |= ImGuiWindowFlags_NoBackground;
ImGui::Begin("##HostWindow", NULL, host_window_flags);
ImGui::PopStyleVar(3);
ImGui::DockSpace(dockspace_id);
ImGui::End();
Interestingly that last block is 99% of what DockSpaceOverViewport()
does. The only difference is that you cannot specify the dockspace identifier when using DockSpaceOverViewport()
, and here you need the dockspace identifier to be able to use the dock builder..
Which is annoying.
If I give you my use of if (DockBuilderGetNode(dockspace_id) == NULL)
in favor of a static variable it becomes simpler by swapping the order:
// Here's some code anyone can copy and paste to reproduce your issue
const ImGuiViewport* viewport = ImGui::GetMainViewport();
ImGuiID dockspace_id = ImGui::DockSpaceOverViewport(viewport);
static bool init = true;
if (init)
{
init = false;
ImGui::DockBuilderRemoveNode(dockspace_id);
ImGui::DockBuilderAddNode(dockspace_id, ImGuiDockNodeFlags_DockSpace);
ImGui::DockBuilderSetNodeSize(dockspace_id, viewport->WorkSize);
ImGuiID dock_id_left = 0, dock_id_right = 0;
ImGui::DockBuilderSplitNode(dockspace_id, ImGuiDir_Left, 0.25f, &dock_id_left, &dock_id_right);
ImGui::DockBuilderDockWindow("Window_1", dock_id_left);
ImGui::DockBuilderFinish(dockspace_id);
}
If seems like we could get the best of both if we could pass an explicit value for dockspace_id to DockSpaceOverViewport()
..
from imgui.
I have decided to add the optional parameter to DockSpaceOverViewport()
, as a small breaking change: 9ebab25
Which means you can use both the simplified code and no static (the problem with the static is that it would reset layout on boot, instead you probably want to only reset layout when there's one, or following some user action).
const ImGuiViewport* viewport = ImGui::GetMainViewport();
ImGuiID dockspace_id = ImGui::GetID("MyDockSpaceId");
const bool init = ImGui::DockBuilderGetNode(dockspace_id) == NULL;
if (init)
{
ImGui::DockBuilderAddNode(dockspace_id, ImGuiDockNodeFlags_DockSpace);
ImGui::DockBuilderSetNodeSize(dockspace_id, viewport->WorkSize);
ImGuiID dock_id_left = 0, dock_id_right = 0;
ImGui::DockBuilderSplitNode(dockspace_id, ImGuiDir_Left, 0.25f, &dock_id_left, &dock_id_right);
ImGui::DockBuilderDockWindow("Window_1", dock_id_left);
ImGui::DockBuilderFinish(dockspace_id);
}
ImGui::DockSpaceOverViewport(dockspace_id, viewport);
ImGui::Begin("Window_1");
ImGui::Text("Text 1");
ImGui::End();
