How do I invoke the Find dialog when using context menu? #5335
Description
I can invoke Find by following the docs:
//************************************
// Method: InitializeFindOptions
// FullName: CWebBrowser::InitializeFindOptions
// Access: public
// Returns: wil::com_ptr<ICoreWebView2FindOptions>
// Qualifier:
// Parameter: const std::wstring & findTerm
//************************************
wil::com_ptr<ICoreWebView2FindOptions> CWebBrowser::InitializeFindOptions(const std::wstring& findTerm)
{
// Query for the ICoreWebView2Environment15 interface.
auto webView2Environment15 = m_pImpl->m_webViewEnvironment.try_query<ICoreWebView2Environment15>();
CHECK_FEATURE_RETURN_NULL(webView2Environment15);
// Initialize Find options
wil::com_ptr<ICoreWebView2FindOptions> find_options;
CHECK_FAILURE(webView2Environment15->CreateFindOptions(&find_options));
CHECK_FAILURE(find_options->put_FindTerm(findTerm.c_str()));
return find_options;
}
//************************************
// Method: ConfigureAndExecuteFind
// FullName: CWebBrowser::ConfigureAndExecuteFind
// Access: public
// Returns: bool
// Qualifier:
// Parameter: const std::wstring & findTerm
//************************************
bool CWebBrowser::ConfigureAndExecuteFind(const std::wstring& findTerm)
{
auto find_options = InitializeFindOptions(findTerm);
if (!find_options) {
return false;
}
// Query for the ICoreWebView2_28 interface to access the Find feature.
auto webView2Environment28 = m_pImpl->m_webView.try_query<ICoreWebView2_28>();
CHECK_FEATURE_RETURN(webView2Environment28);
// Get the Find interface.
wil::com_ptr<ICoreWebView2Find> webView2Find;
CHECK_FAILURE(webView2Environment28->get_Find(&webView2Find));
// By default Find will use the default UI and highlight all matches. If you want different behavior
// you can change the SuppressDefaultDialog and ShouldHighlightAllMatches properties here.
// Start the Find operation with a callback for completion.
CHECK_FAILURE(webView2Find->Start(
find_options.get(),
Callback<ICoreWebView2FindStartCompletedHandler>(
[this](HRESULT result) -> HRESULT
{
if (SUCCEEDED(result))
{
// Optionally update UI elements here upon successful Find operation.
}
else
{
// Handle errors.
}
return S_OK;
}).Get()));
// End user interaction is handled via UI.
return true;
}And then in my editor code I just call m_pWebBrowser->ConfigureAndExecuteFind(L"");.
But, in my context menu event handler I still need to use SendInput:
// ===============================================================
// Find (CTRL + F)
if (!m_itemFind || bFullInit)
{
m_itemFind.reset();
wil::com_ptr<IStream> iconStreamFind;
CHECK_FAILURE(SHCreateStreamOnFileEx(
theApp.GetCommonAppDataFolder() + L"WebView2\\find" + strIconSuffix, STGM_READ, FILE_ATTRIBUTE_NORMAL, FALSE,
nullptr, &iconStreamFind));
CString strMenuText;
strMenuText.LoadString(IDS_STR_MENU_FIND);
CHECK_FAILURE(webviewEnvironment->CreateContextMenuItem(
strMenuText, iconStreamFind.get(),
COREWEBVIEW2_CONTEXT_MENU_ITEM_KIND_COMMAND, &m_itemFind));
CHECK_FAILURE(m_itemFind->add_CustomItemSelected(
Callback<ICoreWebView2CustomItemSelectedEventHandler>(
[](ICoreWebView2ContextMenuItem* sender, IUnknown* args)
{
// m_pWebBrowser->ConfigureAndExecuteFind(L"");
// Create an array of generic keyboard INPUT structures
std::vector<INPUT> vIP(4);
for (int n = 0; n < 4; ++n)
{
vIP.at(n).type = INPUT_KEYBOARD;
vIP.at(n).ki.wScan = 0;
vIP.at(n).ki.time = 0;
vIP.at(n).ki.dwFlags = 0; // 0 for key press
vIP.at(n).ki.dwExtraInfo = 0;
}
vIP.at(0).ki.wVk = VK_CONTROL;
vIP.at(1).ki.wVk = 'F';
vIP.at(2).ki.wVk = 'F';
vIP.at(2).ki.dwFlags = KEYEVENTF_KEYUP;
vIP.at(3).ki.wVk = VK_CONTROL;
vIP.at(3).ki.dwFlags = KEYEVENTF_KEYUP;
SendInput(4, vIP.data(), sizeof(INPUT));
return S_OK;
})
.Get(), nullptr));
}
CHECK_FAILURE(items->InsertValueAtIndex(itemsCount, m_itemFind.get()));
itemsCount++;
// ===============================================================
