|
// This class handles payment requests from clicking on
|
|
// bitcoin: URIs
|
|
//
|
|
// This is somewhat tricky, because we have to deal with
|
|
// the situation where the user clicks on a link during
|
|
// startup/initialization, when the splash-screen is up
|
|
// but the main window (and the Send Coins tab) is not.
|
|
//
|
|
// So, the strategy is:
|
|
//
|
|
// Create the server, and register the event handler,
|
|
// when the application is created. Save any URIs
|
|
// received at or during startup in a list.
|
|
//
|
|
// When startup is finished and the main window is
|
|
// shown, a signal is sent to slot uiReady(), which
|
|
// emits a receivedURI() signal for any payment
|
|
// requests that happened during startup.
|
|
//
|
|
// After startup, receivedURI() happens as usual.
|
|
//
|
|
// This class has one more feature: a static
|
|
// method that finds URIs passed in the command line
|
|
// and, if a server is running in another process,
|
|
// sends them to the server.
|
|
//
