Struct ExportDialog 

pub struct ExportDialog { /* private fields */ }

Export dialog for configuring and executing chart exports

The dialog offers:

• Format selection (PNG, CSV, Clipboard)
• Image dimensions, title, timestamp and transparent background
• File save path entry

The dialog only collects the request; the host performs the export. Use with_formats to offer only the formats the host can produce. The dialog stays open after a request; report its result with mark_success or mark_error.

Example

use egui_charts::ui::export::{ExportDialog, ExportResponse};

let mut export_dialog = ExportDialog::new();

// Open the dialog
export_dialog.open();

// In your egui update loop
match export_dialog.show(ctx) {
    ExportResponse::Export { config, save_path } => {
        // Perform the actual export
        println!("Exporting with config: {:?}", config);
    }
    ExportResponse::Closed => {
        println!("Dialog closed");
    }
    ExportResponse::None => {}
}

Implementations

impl ExportDialog

pub fn new() -> Self

Creates a new export dialog with default configuration

pub fn with_formats(self, formats: &[ExportFormat]) -> Self

Offers only formats, in the given order, for hosts that cannot perform every export. Selects the first of them if the current format is not offered.

pub fn open(&mut self)

Opens the export dialog

This resets the export status to idle and shows the dialog.

pub fn close(&mut self)

Closes the export dialog

pub fn is_open(&self) -> bool

Returns whether the dialog is currently open

pub fn show(&mut self, ctx: &Context) -> ExportResponse

Shows the export dialog and returns the user’s action

This displays a dialog with export configuration options. Returns ExportResponse indicating what action the user took.

Example

let mut dialog = ExportDialog::new();
dialog.open();

match dialog.show(ctx) {
    ExportResponse::Export { config, save_path } => {
        // Perform export
    }
    ExportResponse::Closed => {}
    ExportResponse::None => {}
}

pub fn show_with( &mut self, ctx: &Context, content: impl FnMut(&mut Ui, ExportFormat), ) -> ExportResponse

Shows the dialog with host controls below its title, such as an image scope chooser. content receives the currently selected format; the host keeps its own control state.

pub fn mark_success(&mut self)

Marks the current export as successful

Call this after completing an export to show success status in the dialog.

pub fn mark_error(&mut self, error: String)

Marks the current export as failed with an error message

Call this if an export fails to show the error in the dialog.

Arguments

• error - A description of what went wrong

pub fn reset_status(&mut self)

Resets the export status to idle

impl Default for ExportDialog

fn default() -> Self
