toastsShow

Standard way of showing toasts. For the main window, this is called with null in Window.end().

For floating windows or other widgets, pass non-null id. Then it shows toasts that were previously added with non-null subwindow_id, and they are shown on top of the current subwindow.

Toasts are shown in rect centered horizontally and 70% down vertically.

Parameters

self:*Self: *Self
subwindow_id:?Id: ?Id
rect:Rect.Natural: Rect.Natural

Implementation

pub fn toastsShow(self: *Self, subwindow_id: ?Id, rect: Rect.Natural) void {
    var it = self.toasts.iterator(subwindow_id);
    it.i = self.toasts.indexOfSubwindow(subwindow_id) orelse return;
    var toast_win: dvui.FloatingWindowWidget = undefined;
    toast_win.init(@src(), .{ .stay_above_parent_window = subwindow_id != null, .process_events_in_deinit = false }, .{ .role = .status, .background = false, .border = .{}, .label = .{ .label_widget = .next } });
    defer toast_win.deinit();

    toast_win.data().rectSet(dvui.placeIn(.cast(rect), toast_win.data().rect.size(), .none, .{ .x = 0.5, .y = 0.7 }));
    toast_win.drawBackground();
    toast_win.autoSize(); // affects next frame, always need as toasts can come and go

    var vbox = dvui.box(@src(), .{}, .{});
    defer vbox.deinit();

    while (it.next()) |t| {
        t.display(t.id) catch |err| {
            dvui.logError(@src(), err, "Toast {x}", .{t.id});
        };
    }
}
