Expand description

Input handler adapter for popup events

This trait defines the contract for converting raw input events into popup actions. External projects implement this trait to customize input behavior (rare).

Provided Methods§

Source

fn hit_test(&self, popup_rect: &Rect, mouse_pos: (f64, f64)) -> bool

Test if mouse position is inside popup rect

Source

fn is_outside_click(&self, mouse_pos: (f64, f64), popup_rect: &Rect) -> bool

Test if click was outside popup (for auto-dismiss)

Source

fn mouse_to_item_index( &self, mouse_y: f64, popup_y: f64, item_height: f64, item_count: usize, padding_vertical: f64, ) -> Option<usize>

Convert mouse Y coordinate to menu item index

Source

fn mouse_to_color_index( &self, mouse_pos: (f64, f64), popup_rect: &Rect, grid_cols: usize, swatch_size: f64, grid_spacing: f64, padding: f64, ) -> Option<usize>

Convert mouse position to color grid index

Source

fn adjust_position_to_screen( &self, pos: (f64, f64), size: (f64, f64), screen: (f64, f64), ) -> (f64, f64)

Adjust popup position to keep it on screen
