Toggles module

The imgui_toggle library, adds toggle widgets to dear imgui, like these:

Enabling the module

To enable the toggles module, update your uvproj.yaml so that the toggles key under enabled-modules is set to true like this:

name: "MyProject"
version: "1.0.0.0"
engine-version: "1.0.0.0"
enabled-modules:
  toggles: true

Then, regenerate the modules cache by running the following command:

user $ ./UVKBuildTool --generate <project directory>

After that, refresh your CMake project with cmake ..!

---

Next, in your source file, include the Modules.hpp header:

#include <Modules/Modules.hpp>

Event safety

The entire module is flagged as event safe at All ready.

Testing out the module

In one of your widgets, add the following code to your tick function:

const ImVec4 green(0.16f, 0.66f, 0.45f, 1.0f);
const ImVec4 green_hover(0.0f, 1.0f, 0.57f, 1.0f);

const ImVec4 gray_dim(0.45f, 0.45f, 0.45f, 1.0f);
const ImVec4 gray(0.65f, 0.65f, 0.65f, 1.0f);

// use some lovely gray backgrounds for "off" toggles
// the default will use your theme's frame background colours.
ImGui::PushStyleColor(ImGuiCol_FrameBg, gray_dim);
ImGui::PushStyleColor(ImGuiCol_FrameBgHovered, gray);

static bool values[] = { true, true, true, true, true, true, true, true };
size_t value_index = 0;

const ImVec4 salmon(1.0f, 0.43f, 0.35f, 1.0f);
const ImVec4 green_shadow(0.0f, 1.0f, 0.0f, 0.4f);

// a default and default animated toggle
ImGui::Toggle("Default Toggle", &values[value_index++]);
ImGui::Toggle("Animated Toggle", &values[value_index++], ImGuiToggleFlags_Animated);

// this toggle draws a simple border around it's frame and knob
ImGui::Toggle("Bordered Knob", &values[value_index++], ImGuiToggleFlags_Bordered, 1.0f);

// this toggle draws a simple shadow around it's frame and knob
ImGui::PushStyleColor(ImGuiCol_BorderShadow, green_shadow);
ImGui::Toggle("Shadowed Knob", &values[value_index++], ImGuiToggleFlags_Shadowed, 1.0f);

// this toggle draws the shadow & and the surrounding border's frame and knob.
ImGui::Toggle("Bordered + Shadowed Knob", &values[value_index++], ImGuiToggleFlags_Bordered | ImGuiToggleFlags_Shadowed, 1.0f);
ImGui::PopStyleColor(1);

// this toggle uses stack-pushed style colours to change the way it displays
ImGui::PushStyleColor(ImGuiCol_Button, green);
ImGui::PushStyleColor(ImGuiCol_ButtonHovered, green_hover);
ImGui::Toggle("Green Toggle", &values[value_index++]);
ImGui::PopStyleColor(2);

ImGui::Toggle("Toggle with A11y Labels", &values[value_index++], ImGuiToggleFlags_A11y);

// this toggle shows no label
ImGui::Toggle("##Toggle With Hidden Label", &values[value_index++]);

// pop the FrameBg/FrameBgHover colour styles
ImGui::PopStyleColor(2);

after compiling and running, the result should look like this:

Learning the module

To learn more about this third party library, check out the imgui_toggle GitHub repository

Checking for the module

To check for the module at compile time, use the UIMGUI_TOGGLES_MODULE_ENABLED macro.

Runtime checking can be done using the toggles member of the ModuleSettings struct. More info can be found here.

C API

We provide a C API for the toggles module as part of the cimgui_extra project. To use it, simply include #include <cimgui_extra/cimgui_toggles.h>.
