ImGui Goodies

This is a collection of widgets and utilities for the immediate mode GUI (imgui) that I am developing for the critic2 GUI. Currently, the contents of this repo are:

• imgui_widget.cpp: a collection of small independent widgets, including:

  • SlidingBar: a bar widget that slides when it is grabbed with the mouse.

  • ButtonWithX: a button with an X at the end. Useful for tabs.

  • ResizeGripOther: a resize grip that resizes a window other than the one on which it is drawn.

  • LiftGrip: a grip on the bottom left part of the window rendered in a different color. Responds to grabbing.

  • AttachTooltip: a function that provides delayed tooltips. Tooltips are shown if: i) the mouse hovers over the element for longer than a certain time, passed as argument to the function, ii) the mouse goes from one tooltip element to another, and the tooltip is being shown, or iii) the mouse hovers a tooltip element for longer than t seconds and less than t seconds have elapsed between the time the last tooltip was shown and the current item started being hovered. See example below.

• imgui_dock.cpp: a window docking system. There are three types of windows:

  • Docks (BeginDock()/EndDock()): like normal windows, except they can be docked to the other two window types.

  • Containers (Container()): a window to which docks can be attached as tabs. It has a behavior similar to a browser window.

  • Root containers (RootContainer()): a window to which both containers and docks can be attached. It splits into regions for the different attached windows depending on where they are dropped.

  Most of the functionality of normal ImGui windows is preserved. imgui_dock.cpp uses the widgets in imgui_widget.cpp but is otherwise self-contained.

Some examples are given in the examples subdirectory. Use the compile.sh script to build the whole directory tree.
