Can code stop loading if the loading take too long time?

[slothsimon]

Hi,

I am using cef Branch2623 and I saw CefLoadHandler only have 4 functions: OnLoadingStateChange, OnLoadStart, OnLoadEnd and OnLoadError.

I want to stop loading if the loading(or receiving response from server) take too long time, so how can i do that? Or is there anything I can config the time wait for loading?

Also I want to know if I can make the page show a page used for waiting and when the actual page has loaded then replace the waiting page with the actual page?

Thank you!

You can call CefBrowser.StopLoad method. In OnLoadingStateChange you could post a CEF delayed task (eg. 30sec) using CefPostDelayedTask that would stop loading. In OnLoadigStateChange when page completes you could cancel that task. There is no function in CEF to cancel a task that was already posted, however you could add some additional logic in your code to accomplish such functionality.

This is very useful! I will use it in my program.
Thank you so much!

What about combining a CefPostDelayedTask with a cef_cancelable_callback?
There's an example in the header

I'm testing that and it seems to work. If I don't call cancel() my callback is called and I see my test log output. If I do call cancel, there is no log output.

However, when I don't cancel, I'm getting a message indicating "MojoDiscardableSharedMemoryManagerImpls are still alive. They will be leaked." So I'm not sure the combination is correct.
