Description

This is an implementation of the Dear ImGui library: https://github.com/ocornut/imgui.

Dear ImGui is licensed under the MIT License, see https://github.com/ocornut/imgui/blob/master/LICENSE.txt for more information.

To use Dear ImGui in your project you need to add the ImGui plugin and call require like so: 

require "ImGui"

Current Gideros Dear ImGui version: 1.89.6.

User Guide

  • Double-click on title bar to collapse window
  • Click and drag on lower corner to resize window (double-click to auto fit window to its contents)
  • CTRL+Click on a slider or drag box to input value as text
  • TAB/SHIFT+TAB to cycle through keyboard editable fields
  • CTRL+Tab to select a window
  • CTRL+Mouse Wheel to zoom window contents if io.FontAllowUserScaling is enabled
  • While inputing text:
    • CTRL+Left/Right to word jump
    • CTRL+A or double-click to select all
    • CTRL+X/C/V to use clipboard cut/copy/paste
    • CTRL+Z,CTRL+Y to undo/redo
    • ESCAPE to revert
  • With keyboard navigation enabled:
    • Arrow keys to navigate
    • Space to activate a widget
    • Return to input text into a widget
    • Escape to deactivate a widget, close popup, exit child window
    • Alt to jump to the menu layer of a window

Widgets

Widgets: Color Editor/Picker 

* tip: the ColorEdit* functions have a little color square that can be left-clicked to open a picker, and right-clicked to open an option menu

Widgets: Input with Keyboard 

* If you want to use InputText() with std::string or any custom dynamic string type, see misc/cpp/imgui_stdlib.h and comments in imgui_demo.cpp.
* Most of the ImGuiInputTextFlags flags are only useful for InputText() and not for InputFloatX, InputIntX, InputDouble etc.

Widgets: Regular Sliders 

* CTRL+Click on any slider to turn them into an input box. Manually input values aren't clamped and can go off-bounds.
* Adjust format string to decorate the value with a prefix, a suffix, or adapt the editing and display precision e.g. "%.3f" -> 1.234; "%5.2f secs" -> 01.23 secs; "Biscuit: %.0f" -> Biscuit: 1; etc.
* Format string may also be set to NULL or use the default format ("%f" or "%d").

If you get a warning converting a float to ImGuiSliderFlags, read https://github.com/ocornut/imgui/issues/3361

Widgets: Drag Sliders 

* CTRL+Click on any drag box to turn them into an input box. Manually input values aren't clamped and can go off-bounds.
* For all the Float2/Float3/Float4/Int2/Int3/Int4 versions of every functions, note that a 'float v[X]' function argument is the same as 'float* v', the array syntax is just a way to document the number of elements that are expected to be accessible. You can pass address of your first element out of a contiguous set, e.g. &myvector.x
* Adjust format string to decorate the value with a prefix, a suffix, or adapt the editing and display precision e.g. "%.3f" -> 1.234; "%5.2f secs" -> 01.23 secs; "Biscuit: %.0f" -> Biscuit: 1; etc.
* Format string may also be set to NULL or use the default format ("%f" or "%d").
* Speed are per-pixel of mouse movement (v_speed=0.2f: mouse needs to move by 5 pixels to increase value by 1). For gamepad/keyboard navigation, minimum speed is Max(v_speed, minimum_step_at_given_precision).
* Use v_min < v_max to clamp edits to given limits. Note that CTRL+Click manual input can override those limits.
* Use v_max = FLT_MAX / INT_MAX etc to avoid clamping to a maximum, same with v_min = -FLT_MAX / INT_MIN to avoid clamping to a minimum.
* We use the same sets of flags for DragXXX() and SliderXXX() functions as the features are the same and it makes it easier to swap them.
