Fig. 5 illustrates among the present invention by the COM plug-in part technology and creates the inserter tool hurdle and the process flow diagram of a specific embodiment of the method for visit widget from host program at host program.
As shown in Figure 5, the flow process of creating the inserter tool hurdle at host program by the COM plug-in part technology relates generally to step 1.1-1.8, and the method for visit widget relates generally to step 2.1-2.8 from host program; Specifically comprise:
Step 1.1, host program loads the widget application plug-in, calls the OnConnection function of widget application plug-in IDispatch interface.
Step 1.2, OnConnection function call toolbar creating unit is created the inserter tool column object.
Step 1.3, toolbar creating unit read the toolbar configuration file corresponding with this application (the toolbar configuration filename is used ID exactly) from the toolbar config directory, obtain the configuration information of each button.Widget toolbar configuration file example is as follows:
<？xml?version＝″1.0″encoding＝″UTF-8″？>
<widget_toolbar>
＜widget_button button_name=" checks weather "
icon＝″find_weather.png″widget_id＝″weather″widget_mode＝″desktop″
entry＝″find_wether″>
<param_template>{city:${selected_text}}</param_template>
</widget_button>
＜widget_button button_name=" sends fax "
icon＝″send_fax.png″widget_id＝″fax″widget_mode＝″desktop″
entry＝″init″>
<param_template>{fax_file:${file_name}}</param_template>
</widget_button>
</widget_toolbar>
Above-mentioned configuration file has defined the widget toolbar that contains two buttons, and a button is " checking weather ", and another button is " sending fax ".＜widget_button〉element definition the widget button information, the button_name attribute of this element is a button name, the icon attribute is the button icon filename, the widget_id attribute is the widget sign, be used for determining widget, the widget_window_id attribute is the widget window ID, be used for determining the widget window, the window_entry attribute is a widget window entrance function name, it is the javascript function name of far call,＜widget_button〉element＜param_template〉daughter element defined the parameterized template of entrance function, the entrance function parameterized template is the character string template of JSON (JavaScript ObjectNotation) form, be used to construct the JSON parameter of entrance function, in the entrance function parameterized template, template variable ${xxx} mark, the template variable is the variable part of parameterized template, is used to bind the application context data.The present invention adopts JSON encapsulation widget request message and function input parameter, but those skilled in the art know and also can adopt XML encapsulation widget request message and function input parameter.
Step 1.4, toolbar creating unit recursive call is unified the button creating unit, at every turn according to button arrangement information＜widget_button〉button object of establishment.
Step 1.5, unified button creating unit loads the icon resource file according to the icon file title in the button arrangement information and binds with button object from the icon resource catalogue.
Step 1.6 is unified the button creating unit according to button arrangement information creating widget visit information object, and this mapping object is written in button-widget information mapping Hash table, and wherein key is button ID, and value is a widget visit information object.Widget visit information object is the object instance of widget visit information class (WidgetAccessInfo), the attribute of visit information class comprises: the widget sign, the widget window ID, widget window entrance function title, entrance function parameterized template and context property tabulation, wherein widget identifies, the widget window ID, widget window entrance function title and suction parameter template respectively with＜widget_button the Response Property or the daughter element of element be corresponding, the context property tabulation then is all template parameter titles that extract after the suction parameter template is made an explanation, for example for suction parameter template " { city:${selected_text}} ", the context property that extracts has only a selected_text.
The C++ false code of widget visit information class definition is as follows:
Class WidgetAccessInfo{ //widget visit information class
public:
String widget_id; //widget sign
String widget_window_id; //widget window ID
String entry_function; //widget entrance function title
String paramTemplate; // entrance function parameterized template
List＜string〉context_attr_names; // context property the tabulation that in parameterized template, defines }
Step 1.7, unified button creating unit are the unified button response unit (response function that is each button is all identical) of button binding.
The Application interface that step 1.8, toolbar creating unit are called host program adds the widget toolbar object that creates in the toolbar container of host program to.
Flow process by widget button visit widget window specifically comprises:
Step 2.1, the user clicks the widget button of host program, triggers unified button response unit.
Step 2.2, unified button response unit obtains widget visit information object according to widget button ID from button-Widget information mapping table.
The unified button response unit of step 2.3 calls widget engine agency, and widget visit information object is passed to widget engine agency.
Step 2.4, widget engine agency takes out the context property tabulation from widget visit information object, and based on context attribute obtains context data from the application interface that the host uses, and context data is converted to character string.For example in word, if the text data (selected_text) of context property for selecting, then obtain the literal of selection by application-＞GetSelection () function, if context property is current file full name (full_file_name), then obtain file full name by application-＞GetFullName ().Possible context property comprises at least: current application title (app_name), current file full name (full_file_name, contain the path), current file title (file_name does not contain the path), current file path (file_path), the literal of selecting (selected_text), zone (selected_region), current page (current_page), the current mouse position (current_mouse_point) selected.
Step 2.5, widget engine agency generates the widget request message according to widget visit information object and application context data, and the widget request message is sent to widget engine (for example the striding course communication mechanism adopts the windows message mechanism, also can adopt the striding course communication technologys such as shared drive, socket to communicate by letter with the widget engine) by the striding course communication mechanism.Adopting the windows message mechanism with the striding course communication mechanism is that example describes:
1) widget engine agency gets speech suction parameter template from widget visit information object, and the template variable in the parameterized template is replaced to application context data character string accessed in step 2.4, obtains entrance function parameter character string.For example for suction parameter template " { city:${selected_text}} ", if the value of context data selected_text is " Guangzhou ", so after the Can Shuo ${selected_text} replacement to the suction parameter template, obtain the parameter character string " { city: Guangzhou } " of entrance function, it is the JSON character string of standard, and the JavaScript engine that can be met the W3C standard is discerned.
2) widget engine agency concatenates into the widget request message according to widget visit information object with entrance function parameter character, and the widget request message is the JSON format messages, and structure is as follows:
{
widget_id:””，
widget_window_id:””，
entry_function:””，
param_obj:””
}
In the widget request message, widget_id, widget_window_id and entry_function source and widget visit information object, the param_obj attribute is an entrance function parameter character string.Suppose to have generated the widget toolbar based on above-mentioned configuration file in word, and the user has clicked " checking weather " button, the widget request message of Sheng Chenging is as follows so:
{
widget_id:”weather”，
widget_window_id:”weather.today”，
entry_function:”find_weather”，
Param_obj: " { city: Guangzhou } "
}
3) obtain the handle that the widget engine implies window.
4) the COPYDATA construction packages widget request message by windows, the message subsystem by windows sends WM_COPYDATA message to the implicit window of widget engine.
5) the message subsystem finds the widget engine to imply window by window handle, calls the window treatments function of implicit window.
Step 2.6, window treatments function are taken out the widget request message from the COPYDATA structure, the widget request message is passed to the widget call unit, request call target widget.
Step 2.7, the widget call unit obtains target widget according to the widget sign from the widget manager, status information according to target widget is carried out respective handling: if target widget does not install, then return " widget does not exist " message, do not do subsequent treatment to widget engine agency; If target widget does not trigger as yet, then trigger widget; If target widget triggers, then the display status information with widget writes in the widget display status register, comprises the display mode of widget, the size and the position of widget window.
Step 2.8, the entrance function of widget call unit invocation target widget also is presented at widget the top layer of desktop.
1) if specified entrance function in the widget request message, the specified javascript function of script object (attribute of document object) call entry function (entry_function) attribute by target widget then, and with entrance function parameter character string (param_obj) directly as the javascript function parameters;
2) display mode with target widget is made as by the specified display mode of widget request message, and the window object by target widget moves on to center Screen with the window of target widget then, and top set shows.In an embodiment of the present invention, the display mode of widget is by DIV figure layer control, every kind of display mode all have with respect to DIV figure layer, change the figure layer that display mode only need show corresponding display mode, and the figure layer of other display mode hidden;
3) after the user browses or uses widget, click the stop push-button on the widget, show state before the widget call unit reverts to widget, promptly from the widget display status register, read the show state (size of display mode, widget window and position) before of widget, the display mode of restore target widget, the window object of invocation target widget recovers window size and the position of target widget.
The invention provides a kind of in application program the method for fast access widget, this method is by embedding the widget toolbar in application program, can satisfy user easily and fast visit widget in common application program, thereby need not between application window and widget window, frequently to switch.In addition, this method can also keep the original layout of widget constant, and application programs and widget change little, satisfy the consistance of user's use, thereby obtain higher acceptance.
