# fltk-theme
A theming crate for fltk-rs.
- The widget themes are based on work by [Remy Oukaour](https://github.com/roukaour/viz-brain-visualizer) and [Rangi42](https://github.com/Rangi42/tilemap-studio).
- The color themes are based on work by [Greg Ercolano](https://groups.google.com/g/fltkgeneral/c/3A5VC_854ok/m/sDpJsmuLBAAJ).
- Some of the widget schemes are based on work by the NTK GUI library, others are nouveau.
## Usage
```toml
[dependencies]
fltk = "1.2"
fltk-theme = "0.2"
```
## Example
Setting the color theme:
```rust
use fltk::{prelude::*, *};
use fltk_theme::{ColorTheme, color_themes};
fn main() {
let a = app::App::default().with_scheme(app::Scheme::Gtk);
let theme = ColorTheme::from_colormap(color_themes::BLACK_THEME);
theme.apply();
let mut win = window::Window::default().with_size(400, 300);
let mut btn = button::Button::new(160, 200, 80, 40, "Hello");
btn.set_color(btn.color().lighter());
win.end();
win.show();
a.run().unwrap();
}
```
Setting the widget theme:
```rust
use fltk::{prelude::*, *};
use fltk_theme::{widget_themes, WidgetTheme, ThemeType};
fn main() {
let a = app::App::default();
let widget_theme = WidgetTheme::new(ThemeType::AquaClassic);
widget_theme.apply();
let mut win = window::Window::default().with_size(400, 300);
let mut btn = button::Button::new(160, 200, 80, 30, "Hello");
btn.set_frame(widget_themes::OS_DEFAULT_BUTTON_UP_BOX);
win.end();
win.show();
a.run().unwrap();
}
```
Setting the widget scheme:
```rust
use fltk::{prelude::*, *};
use fltk_theme::{WidgetScheme, SchemeType};
fn main() {
let a = app::App::default();
let widget_scheme = WidgetScheme::new(SchemeType::Clean);
widget_scheme.apply();
let mut win = window::Window::default().with_size(400, 300);
let mut btn = button::Button::new(160, 200, 80, 30, "Hello");
win.end();
win.show();
a.run().unwrap();
}
```

## Widget Schemes
These provide schemes for widgets without color theming. Currently there are 6 schemes:
- Aqua: Tries to mimic the modern MacOS's styles.
- 
- Fluent: Tries to mimic Window's 10 styles.
- 
- 
- Clean: Taken from NTK's clear scheme.
- 
- Crystal: Taken from NTK's crystal scheme.
- 
- Gleam: Taken from NTK's gleam scheme.
- 
- SvgBased: This overrides FLTK's Base scheme round/rounded/oval FrameTypes which are drawn using scalable vector graphics.
