QTP 自定义方法将IE最大化最小化

This article demonstrates a quick tip to activate, minimize or maximize browsers. Unlike a Standard Windows Window object, Browser does not support theActivate, Minimize, Maximize methods. Therefore, we can create our custom function and tie it with the Browser object using RegisterUserFunc.

The only trick is to retrieve the Browser Handle and substitute the handle in the description of a Window object, and use the Window’s Activate method instead.

ACTIVATE BROWSER

[vb] view plaincopyprint?

1. Function BrowserActivate(Object)  
2.     Dim hWnd  
3.    
4.     hWnd = Object.GetROProperty("hwnd")  
5.    
6.     On Error Resume Next  
7.         Window("hwnd:=" & hWnd).Activate  
8.    
9.         If Err.Number <> 0 Then  
10.             Window("hwnd:=" & Browser("hwnd:=" & hWnd).Object.hWnd).Activate  
11.             Err.Clear  
12.         End If  
13.     On Error Goto 0  
14. End Function  
15.    
16. RegisterUserFunc "Browser", "Activate", "BrowserActivate"  

After registering the BrowserActivate function with the Browser object as Activate we can use it just like we would use it for a Window object:

[vb] view plaincopyprint?

1. Browser("title:=Relevant Codes.*").Activate  

BrowserActivate can be extended to maximize and minimize a browser window as well. The only extra statement to be included in the function would be the maximize and minimize methods of the window object.

MINIMIZE BROWSERS

[VB] VIEW PLAINCOPYPRINT?

1.   

[VB] VIEW PLAINCOPYPRINT?

1. FUNCTION BROWSERMINIMIZE(OBJECT)  
2.     DIM HWND  
3.    
4.     HWND = OBJECT.GETROPROPERTY("HWND")  
5.    
6.     ON ERROR RESUME NEXT  
7.         WINDOW("HWND:=" & HWND).ACTIVATE  
8.    
9.         IF ERR.NUMBER <> 0 THEN  
10.             HWND = BROWSER("HWND:=" & HWND).OBJECT.HWND  
11.             WINDOW("HWND:=" & HWND).ACTIVATE  
12.             ERR.CLEAR  
13.         END IF  
14.    
15.         WINDOW("HWND:=" & HWND).MINIMIZE  
16.     ON ERROR GOTO 0  
17. END FUNCTION  
18.    
19. REGISTERUSERFUNC "BROWSER", "MINIMIZE", "BROWSERMINIMIZE"  

MAXIMIZE BROWSERS

[vb] view plaincopyprint?

1. Function BrowserMaximize(Object)  
2.     Dim hWnd  
3.    
4.     hWnd = Object.GetROProperty("hwnd")  
5.    
6.     On Error Resume Next  
7.         Window("hwnd:=" & hWnd).Activate  
8.    
9.         If Err.Number <> 0 Then  
10.             hWnd = Browser("hwnd:=" & hWnd).Object.hWnd  
11.             Window("hwnd:=" & hWnd).Activate  
12.             Err.Clear  
13.         End If  
14.    
15.         Window("hwnd:=" & hWnd).Maximize  
16.     On Error Goto 0  
17. End Function  
18.    
19. RegisterUserFunc "Browser", "Maximize", "BrowserMaximize"  

If you would like to use the above 3 methods through a single function or class, they can be coupled together through Execute statements or through If-Then or Switch-Case blocks. Happy reading!
