custom-component

问题 I'm writing a custom component for react-leaflet. It is an editable popup, with a few other features. Here is a codesandbox for an example.. The source code for the component is here. This example just does an import EditablePopup from 'my-react-leaflet-popup-plugin' , which is a .js file in my project. Works well. I am trying to bundle this using webpack to package it as a node module so that others can use it. It compiles without issue. You can see my webpack.config.js here. I am then using

问题 I am developing various components, and regularly run into the need to have a property that has a "one-to-many" relationship, component-to-property-member. The components are often visual components, but not always, and sometimes need to be registered with the IDE (i.e. use the Property Inspector), but not always. I find myself unsure of which route to take when setting up these properties -- using an array property, a TList, a TStringList, a TCollection, or something else altogether (perhaps

问题 we are still in a JSF 1.2 to 2.0 migration scenario and we are now facing a problem related to c:set or ui:param variables used inside an EL expression. Here are the facts. There is a button as composite component: <cc:interface name="button" shortDescription="A button."> ... <cc:attribute name="disabled" required="false" default="false" shortDescription="The disabled flag." /> ... </cc:interface> <cc:implementation> <ice:commandButton ... disabled="#{cc.attrs.disabled}" ... /> </cc

问题 I want to write a classLoader that can help me implement customized classes and ultimately a whole component at run time. Right now I'm in process of loading the class.

问题 I originally posted the question to check for presence of either ADO.NET/OLEDB connection types. That being resolved, I'd like to know, how to change the code when it comes to inserting to the DB. For example, when the connection type is ADO.NET we use the "Transaction" in the connection type. SqlConnection connection = (SqlConnection)connections[_connectionName].AcquireConnection(transaction); Now if I have the OLEDB connection (instead of ADO.NET), I'd like to handle that situation in this

问题 I am developing a website in Joomla 3.0. What I am trying to do is to create a custom login form. The reason I want to do that is to enable users to select the user group they want to be put in while they are registering. So I need to create a dropdown box in the login form.

So please, if you have

问题 I tried to create a custom rating bar. I don't use style because I only use this once. So, I created a layer-list in the drawable folder (its name is custom_rating_bar.xml ): <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@android:id/background" android:drawable="@drawable/custom_icon_empty"/> <item android:id="@android:id/secondaryProgress" android:drawable="@drawable/custom_icon_empty"/> <item android:id="@android:id/progress" android:drawable="
