EventNotifier for Browser Control

Chris Howell — Tue, 14 Sep 2021 07:19:39 GMT

Hi, Archicad dev teams
I am developing the Add-on in Archicad 24 using Browser control.
I tried to handle downloading event but I can't build the project.
Please help me.

This is my code.

static bool HandleDownloadingEvent(const DG::BrowserBase& source, const DG::BrowserDownloadingArg &args); void BrowserPalette::InitBrowserControl() { GS::UniString url = this->GetSiteUrl(); DBASSERT(!url.IsEmpty()); this->m_browser.LoadURL(url); this->m_browser.DisableContextMenu(); this->RegisterAPIJavaScriptObject(); this->m_browser.onDownloading += DG::EventNotifier<DG::BrowserBase, DG::BrowserDownloadingArg, bool, true>::Runnable(&BrowserPalette::HandleDownloadingEvent); } bool BrowserPalette::HandleDownloadingEvent(const DG::BrowserBase& source, const DG::BrowserDownloadingArg &args) { if (source.GetDefaultEventTarget() == nullptr) return false; if (args.isComplete) { return true; } return false; } Error: error C2338: Second argument must be EventArg&! error C2440: '<function-style-cast>': cannot convert from 'const std::function<bool (const DG::BrowserBase &,DG::BrowserDownloadingArg &)>' to 'DG::EventNotifier<DG::BrowserBase,const DG::BrowserDownloadingArg,bool,true>::RunnableHelper'

Kind Regards,
Chris

Please try to add the event handler with Add instead of +=.

And use a non static member function:

class BrowserPalette: ..., { ... bool HandleDownloadingEvent (const DG::BrowserBase& source, const DG::BrowserDownloadingArg& args); }; BrowserPalette::BrowserPalette (...) { browser.onDownloading.Add (&BrowserDialog::HandleDownloadingEvent, this); }
