Specifying Cell format for WritableHyperlink using jxl for java -

-

I am using jxl (a java based API for MS Excel file manipulation) to create Excel report. I am inserting hyperlink like this 
  // Sheet is WritableSheet // To add hyperlink to 0,0 of Sheet. WritableHyperlink hl = New WritableHyperlink (0, 0, "http: //Www.google.com", "Home Page"); Sheet.addHyperlink (hl);   
 This works fine, but this data displays in the default cell format, which is white color and blue font. Is there any way by which I can specify the cell format for this hyperlink, such as the label or the number it is important because it opens the hyperlink error screenshot, so according to the specification, the cell should be in red color.  
 Thanks   
 
 
 What type of hyperlink is you for the same cell Like, set a label like:  
  WritableHyperlink hl = new WritableHyperlink (0, 0, new URL ("http://www.google.com")); Sheet.addHyperlink (hl); WritableFont redFont = New WritableFont (WritableFONT.ARIAL); RedFont.setColour (Color.RED); Writeable cellform cell format = new writable fillmate (redfonts); Label label = new label (0, 0, "home page", cell format); Sheet.addCell (label);

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
