selection

问题 I am wondering how you can change the cursor position in draft.js after having done an text insertion on key command. Therefore I am currently using _handleKeyCommand(cmd) to insert a custom text block whenever the user presses a specific button. Next I tried the following: currentState = this.state.editorState; var selectionState = this.state.editorState.getSelection().getStartKey(); this.setState({editorState: EditorState.forceSelection(currentState, selectionState)}); But this keeps

问题 If a NSTextView contains the following: SELECT someTable.someColumn FROM someTable And a user double-clicks someTable.someColumn , the entire thing gets selected (both sides of the period). In this specific case (a query editor), it would make more sense for either the someTable or the someColumn to be selected. I've tried looking around to see if I can figure out a way to customize the selection, but I have been unable to so far. At the moment what I'm thinking of doing is subclassing

问题 Is this possible? I want selected text to have a solid background, not a transparent background. opacity: 1 does not do it because there must be a standard override from the browser (or something like that). ::-moz-selection { background: #fff; color: #000; } ::selection { background: #fff; color: #000; } body { color: #fff; font-family: sans-serif; line-height: 2em; } div { padding: 2em; background: #F8372A; text-align: center; } <div> <h1>HEY!</h1> <p>why is my background not<br/><strong

问题 I have a QCalendarWidget and some days of month are colored (for example holidays are red). When I select a day which is colored, selection clears the color and I can't see it's original color. But when I deselect that day - color is back. Please see in pictures. Is there a way to keep color even if a day is selected? I know that there is a way to do this for QTableView with delegates, but I can't find anything like this for QCalendarWidget . Any Ideas? Thank you for your time. 回答1: You can

问题 Ive been working on selection sort algorithms, just wanted to know the step by step method on working out using the selection sort algorithm. Just wanted to know if the below is correct Array: 6, 20, 12, 8 1st phase: n=0 6, 20, 12, 8 (no swap) 2nd phase: n=1 6, 8, 12, 20 3rd phase: n=2 6, 8, 12, 20 (no swap) 回答1: Yes You are right arr[] = 6, 20, 12, 8 // Find the minimum element in arr[0...3] // and place it at beginning // 6 is minimum and at its place so no swap 6, 20, 12, 8 // Find the

问题 I hope this wasn't asked before, I couldn't find an easy solution in MSDN or here. The windows phone 8.1 application is deployed in more than one language. To do so I use the default language (english) in Strings\en-US\Ressources.resw and installed the Multilingual App Toolkit with all further languages added there. To change the language, I have the following code: private void changeLang(string cul) { Windows.Globalization.ApplicationLanguages.PrimaryLanguageOverride = cul; Windows

问题 I followed this tutorial on object selection. However, when I import my .obj assets and try to select/highlight them, it appears that the raycaster does not pick them up. Nothing happens when my mouse clicks on my .obj object. I added the necessary colliders (box collider even mesh collider) and nothing happens. What am I doing wrong? I didn't change the code from the source provided. I just imported my object file to the scene and added the necessary physics. All I want to do is highlight my

问题 In my XAML file, I have a ListBox declared like this : <ListBox x:Name="lstDeck" Height="280" ItemsSource="{Binding Path=Deck}" > <ListBox.ItemTemplate> <DataTemplate> <ListBoxItem Content="{Binding}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> In my view model, Deck is an ObservableCollection, so that binding directly displays the content of my collection. But when I have several value that hold the same value (for example "10" six times), the selection in the ListBox has a weird

问题 I am fairly new to XPATH and need to return a value from multiple XML objects when a certain node is equal to one of two values. The solution also needs to be namespace agnostic using local-name(). Given the following XML, I am looking to return all of the values of "B" where "A" is equal to either "4" or "5". <?xml version="1.0"?> <element> <A>3</A> <B>Value 1</B> </element> <element> <A>4</A> <B>Value 2</B> </element> <element> <A>5</A> <B>Value 3</B> </element> I have tried many iterations
