FindTextAsync examples?

[Andrew roden]

Are there any examples of implementing the FindTextAsync in 6.1?

Hello Andrew,

Thank you for posting this question.  What you should do first is call SetFindTextHandler:

This takes in a FindTextAsyncHandler:

Then when you call FindTextAsync, that FindTextAsyncHandler delegate will be called:

For example, code to search for the string "and" and select the first result would look something like:

void  MyFindTextHandler(bool success, Selection select, void *custom_data)
{
    if (success)
    {
        PDF::PDFViewCtrl* view = (PDF::PDFViewCtrl*)custom_data;
        view->Select(select);
    }
}

...

PDF::PDFViewCtrl *view = ...
view->SetFindTextHandler(MyFindTextHandler, (void*)view);
view->FindTextAsync("and", false, false, false, false);
