This defines the path where the WebView2 stores the user data. If empty `%APPDATA%\[BinaryName.exe]` will be used.
### Theme
Name: Theme
Type: `windows.Theme`
Minimum Windows Version: Windows 10 2004/20H1
This defines the theme that the application should use:
| Value | Description |
| --------------- | ----------- |
| SystemDefault | *Default*. The theme will be based on the system default. If the user changes their theme, the application will update to use the new setting |
| Dark | The application will use a dark theme exclusively |
| Light | The application will use a light theme exclusively |
### CustomTheme
Name: CustomTheme
Type: `windows.CustomTheme`
Minimum Windows Version: Windows 10/11 2009/21H2 Build 22000
Allows you to specify custom colours for TitleBar, TitleText and Border for both light and dark mode, as well as
when the window is active or inactive.
#### CustomTheme
The CustomTheme struct uses `int32` to specify the colour values. These are in the standard(!) Windows format of:
`0x00BBGGAA`. A helper function is provided to do RGB conversions into this format: `windows.RGB(r,g,b uint8)`.
NOTE: Any value not provided will default to black.
```go
type ThemeSettings struct {
DarkModeTitleBar int32
DarkModeTitleBarInactive int32
DarkModeTitleText int32
DarkModeTitleTextInactive int32
DarkModeBorder int32
DarkModeBorderInactive int32
LightModeTitleBar int32
LightModeTitleBarInactive int32
LightModeTitleText int32
LightModeTitleTextInactive int32
LightModeBorder int32
LightModeBorderInactive int32
}
```
Example:
```go
CustomTheme: &windows.ThemeSettings{
// Theme to use when window is active
DarkModeTitleBar: windows.RGB(255, 0, 0), // Red
DarkModeTitleText: windows.RGB(0, 255, 0), // Green
DarkModeBorder: windows.RGB(0, 0, 255), // Blue
LightModeTitleBar: windows.RGB(200, 200, 200),
LightModeTitleText: windows.RGB(20, 20, 20),
LightModeBorder: windows.RGB(200, 200, 200),
// Theme to use when window is inactive
DarkModeTitleBarInactive: windows.RGB(128, 0, 0),
DarkModeTitleTextInactive: windows.RGB(0, 128, 0),
DarkModeBorderInactive: windows.RGB(0, 0, 128),
LightModeTitleBarInactive: windows.RGB(100, 100, 100),
LightModeTitleTextInactive: windows.RGB(10, 10, 10),
LightModeBorderInactive: windows.RGB(100, 100, 100),
