方法详细资料

onBeforePopup

public boolean onBeforePopup(CefBrowser browser,
                    String target_url,
                    String target_frame_name)

从接口复制的说明: CefLifeSpanHandler

Called on the IO thread before a new popup window is created. The |browser| and |frame| parameters represent the source of the popup request. The |target_url| and |target_frame_name| values may be empty if none were specified with the request. The |popupFeatures| structure contains information about the requested popup window. To allow creation of the popup window optionally modify |windowInfo|, |client|, |settings| and |no_javascript_access| and return false. To cancel creation of the popup window return true. The |client| and |settings| values will default to the source browser's values. The |no_javascript_access| value indicates whether the new browser window should be scriptable and in the same process as the source browser.

指定者:

onBeforePopup 在接口中 CefLifeSpanHandler

参数:

browser - The source of the popup request.

target_url - May be empty if none is specified with the request.

target_frame_name - May be empty if none is specified with the request.

返回:

To cancel creation of the popup window return true.

onAfterCreated

public void onAfterCreated(CefBrowser browser)

从接口复制的说明: CefLifeSpanHandler

Handle creation of a new browser window.

指定者:

onAfterCreated 在接口中 CefLifeSpanHandler

参数:

browser - The browser generating the event.

runModal

public boolean runModal(CefBrowser browser)

从接口复制的说明: CefLifeSpanHandler

Called when a modal window is about to display and the modal loop should begin running. Return false to use the default modal loop implementation or true to use a custom implementation.

指定者:

runModal 在接口中 CefLifeSpanHandler

参数:

browser - The browser generating the event.

返回:

false to use the default modal loop implementation.

doClose

public boolean doClose(CefBrowser browser)

从接口复制的说明: CefLifeSpanHandler

Called when a browser has received a request to close. If CEF created an OS window for the browser returning false will send an OS close notification to the browser window's top-level owner (e.g. WM_CLOSE on Windows, performClose: on OS-X and "delete_event" on Linux). If no OS window exists (window rendering disabled) returning false will cause the browser object to be destroyed immediately. Return true if the browser is parented to another window and that other window needs to receive close notification via some non-standard technique.

指定者:

doClose 在接口中 CefLifeSpanHandler

参数:

browser - The browser generating the event.

返回:

false will send an OS close notification to the browser window's top-level owner.

onBeforeClose

public void onBeforeClose(CefBrowser browser)

从接口复制的说明: CefLifeSpanHandler

Called just before a browser is destroyed. Release all references to the browser object and do not attempt to execute any methods on the browser object after this callback returns. If this is a modal window and a custom modal loop implementation was provided in runModal() this callback should be used to exit the custom modal loop. See doClose() documentation for additional usage information.

指定者:

onBeforeClose 在接口中 CefLifeSpanHandler

参数:

browser - The browser generating the event.
