问题 I would like to adapt a combo box component's CSS. The combo box has my style class custom1 added which should disable border radius for left corners. In my shared-styles.html , I tried to adapt CSS properties: .custom1 { --lumo-border-radius: 0px; } This is changing the styles but it is not exactly what I want. According to docs, I should follow this wiki to apply local scope styles for the web component. So, I tried: <custom-style> <style> ... </style> </custom-style> <dom-module id="my

问题 I am trying to have a auto refresh feature for the grid which basically, updates the grid with latest data from the server every 'n' seconds.

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 5 years ago . I just tried to play with Vaadin Framework and it seems to me very easy to use. Plus what I like about his framework is that it is built on top of Google Web Toolkit (GWT). What do you think, should I continue using this framework or it's better to stick with GWT? 回答1: Hey.

问题 How do I add a 2x click listener on a vaadin grid? When I 2x click on it, it takes me to another page. Example would be most appreciated. 回答1: With the MouseEvent you can simply ask for a double click. See here #MouseEvents.ClickEvent.html#isDoubleClick() 回答2: Here is an example: grid.addItemClickListener(listener -> { if (listener.getMouseEventDetails().isDoubleClick()) // pass the row/item that the user double clicked // to method doStuff. doStuff(l.getItem()); } ); 来源： https:/

问题 I have implemented a poor-mans-searchbox using a combobox. The search expression is typed into the textfield and the user press enter. Then the search expression is added to the combo model, this is caught in the eventhandler which then runs the search, empties the combo list and populates it with the searchresults instead. However, the user then need to open the combo list manually (by pressing the little down-arrow) to see the result. It'd be nice to open the list automatically, but I haven
