+# RainMeterAutoLayout
+
+A rainmeter skin that will automatically switch to a specific layout on resolution changes. I often need to connect / disconnect multiple monitors, and Rainmeter seems doesn't provide a way to auto switch the layout when that happens, I will need to manually switch layout everytime that happens, which is annoying.
+
+So far I only found a tool named [RainRez](https://forum.rainmeter.net/viewtopic.php?t=10471) that offers similar functionality, but it only checks the default monitor's resolution, and requires running a separate .exe file, therefore I decided to make my own...
+
+## Installation
+
+1. Download the `.rmskin` file from the [Releases](https://github.com/JoeSiu/RainMeterAutoLayout/releases/latest) section.
+2. Double click the `.rmskin` file to install the skin.
+
+## Usage
+
+1. To utilize AutoLayout, you must first load the `AutoLayout/Main.ini` for each layout you want to switch to, and then save the layout.
+2. Edit the configuration files located at `~YourRainMeterSkinFolder\AutoLayout\@Resources\Variables.inc`, specifically the `LayoutMap` variable.
+
+### Configs

+| `EnableDefaultLayout` | Determines whether to fallback to the `DefaultLayout` if no resolution layout is found after a resolution change.                      | 0       |

+- The term "virtual screen" refers to the screen that encompasses all display monitors. For example, if two horizontally aligned monitors with resolutions of `2560x1440` and `1920x1080`, the virtual screen size would be `4480x1440`.
+- In the `LayoutMap` variable, if for example value `"4480x1440=Layout1|2560x1440=Layout2|1920x1080=Layout3"` is provided, it means that if both monitor is connected, then it will switch to `Layout1`; if only the 1440p monitor is connected, then it will switch to `Layout2`; and if only the 1080p monitor is connected, then it will switch to `Layout3`.
