Python xlwt - making a column readonly (cell protect)

徘徊边缘 提交于 2019-12-01 03:09:03
问题 Is there a way to make a particular cell read-only/write protected in python xlwt? I know there's is a cell_overwrite_ok flag which does not allow to overwrite contents of cells (all cells) but can this be done on cell by cell basis. Thanks, Sun 回答1: Excel cells have a locked attribute that is enabled by default. However, this attribute is only invoked when the worksheet's protection attribute is also set to True . If the worksheet is not protected, the locked attribute is ignored. Therefore,

I have an anchor like this <a href='#' onclick='return showform(this)'>click me</a> But I want to be able to override the onclick function, how to do this in jquery? because it seems when I add $('a').click( function() { alert('hi there!'); } ); the new click handler is not overriding the old one Have you tried something like this: $("a").removeAttr("onclick"); In your case the onCick event is overriding the jQuery one. What you might be able to do is: $('a').unbind('click').click(function(){ alert('why hello there children.'); }) But I believe this would have to be included after the <a href=

PHP - override function with different number of parameters

。_饼干妹妹 提交于 2019-12-01 02:45:56
I'm extending a class, but in some scenarios I'm overriding a method. Sometimes in 2 parameters, sometimes in 3, sometimes without parameters. Unfortunately I'm getting a PHP warning. My minimum verifiable example: http://pastebin.com/6MqUX9Ui <?php class first { public function something($param1) { return 'first-'.$param1; } } class second extends first { public function something($param1, $param2) { return 'second params=('.$param1.','.$param2.')'; } } // Strict standards: Declaration of second::something() should be compatible with that of first::something() in /home/szymon/webs/wildcard

Sealed keyword in association with override

左心房为你撑大大i 提交于 2019-12-01 02:21:17
Is it always necessary to follow the sealed keyword with override in the signature of a method like the below code: public sealed override string Method1(){.....} I mean, if I want to "seal" the method within the base class without overriding, is the override keyword still necessary? Sealing a method only makes sense if you override it. What happens here is the following: You are overriding a method from a base class ( override ) and tell the compiler that classes derived from your class are no longer allowed to override this method ( sealed ). If the method is a new one declared by you in

In Java, is it possible to override methods if return types are respectively a primitive and its wrapper class?

梦想的初衷 提交于 2019-12-01 02:09:58
While working with the idea of overriding and overridden methods in Java I have noticed that there is some flexiblity given for the return types of such methods. Here is a bit of theory: "The return type of an overriding method in the derived class can be the same, or a subclass of the return type of the overridden method in the base class. The return type of such an overriding method is known as a covariant return type." Example below supposes that B extends A. Method in A: public Object some_method() {....} Method in B: public Integer some_method() {....} So, we see that some_method() in B

How to identify override method in Java byte code?

偶尔善良 提交于 2019-12-01 02:04:42
问题 I'm now focusing on a project requiring insight of Java byte code. With the help of bcel, I can now complete most of the work. One point that I'm now not clear is how to identify a sub-class method override its base code? Is there any attribute recorded in the .class file associated with a method indicating this overriding relationship or should I go backwards to its base class can compare method signatures? Any hints will be highly appreciated. 回答1: You need to look up the hierarchy chain-

How do I override a method in a subclass?

允我心安 提交于 2019-12-01 01:27:26
I have an inventory program written to include an array and a method to calculate total cost for all inventory items entered. I now have to include a subclass that overrides the original to include "one unique feature". I created a new file named ItemDetails to set up for the subclasses of the original Item. I need to include one unique feature and calculate the value of the inventory and calculate a 5% restocking fee in this subclass. Do I just transfer some of the relevant lines into the other class? Or do I write some code twice? I don't know what to do next. Any help is useful. Thanks.

Using the MultiView component in an area containing TWebBrowser, the component overrides the MultiView . Is there a way to fix this? Usage: Delphi XE8 Update 1 There is no code in this first test. All configuration is visual with MultiView Use TWebBrowser.MakeScreenshot and hide TWebBrowser when the TMultiView opens up.

Overriding a private method with Reflection

邮差的信 提交于 2019-12-01 01:07:12
问题 Is it possible to override a private method by using Reflection in .NET 3.5? 回答1: Well, it would need to be virtual to be possible to override it (by writing a dynamic type that inherits from the class), and you can't have a private virtual (it makes no sense). You could perhaps override an internal virtual , but I suspect even this may hit security issues. So ultimately, I'd say no. 回答2: Not by using Reflection alone. Perhaps the best you could do is to use Reflection, combined with
