Chapter Twenty-one — WebView Interface (continued)
Overview
The WebViewWait function processes application messages, allowing the WebView to process callbacks and handle user interaction.
Syntax/Parameters
Syntax
int = WebViewWait ( handle hWVO, [int duration] );
Parameters
hWVO
A handle specifying a WebView Object.
duration
An optional int specifying the amount of time to wait in milliseconds. The default value is 1000.
Return Value
An int as ERROR_NONE (0) or a formatted error code on failure. An ERROR_TIMEOUT will be returned if the full duration is waited.
Remarks
This function does not actually wait for any specific event but instead waits for the WebView to perform any user interactions and or callbacks. Because the WebView requires the main application thread to process messages using this function is important for the stability of WebView. For example, while waiting for a JavaScript function the following code could be used:
result = JavaScriptRun(hWebView, myJavaScript);
ix = 0;
while (JavaScriptIsComplete(result) == false) {
WebViewWait(hWebView, 1000);
ix++;
if (ix >= 10) {
break;
}
}
This allows for the WebView to process and the script to gracefully wait for completion of a JavaScript operation.
