Cancellable wait or find

[Gintaras]

Added in v0.18. Thank you.

The type of the timeout parameter of wait functions now is Seconds instead of double. It allows to pass wait options and cancellation token.
 

Code:

Copy      Help

var cts = new CancellationTokenSource(2000);
try { wait.until(new Seconds(0) { Cancel = cts.Token }, () => false); }
catch (OperationCanceledException) { print.it("canceled"); }

Code:

Copy      Help

CancellationTokenSource cts = null;
int iTask = 0;

var b = new wpfBuilder("Window").WinSize(400);
b.R.AddButton("Start", _ => { cts?.Cancel(); cts = new(); Task.Run(_Task); });
b.R.AddButton("Cancel", _ => { cts?.Cancel(); });
b.R.AddOkCancel();
b.End();
b.Window.Closed += (_, _) => { cts?.Cancel(); };
if (!b.ShowDialog()) return;

void _Task() {
    using var osd = osdText.showTransparentText($"Waiting, task {++iTask}", -1, xy: new(y: .6f));
    try { wait.until(new Seconds(0) { Cancel = cts.Token }, () => false); }
    catch (OperationCanceledException) { print.it("canceled"); }
}
