Available since: Gideros 2020.9
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.
