selection

问题 I have a JTable in java which contains 5 rows(lets say) UI. I select 2 rows and those 2 rows are highlighted and then I click on a button. Now in the code, on that button I am disabling the row selection so that I will not be able to select any more rows once I have clicked that button. But the problem is the selection of those 2 rows is getting cleared means that in the code I can access those 2 selected rows but in the UI those rows are not highlighted after disabling. Is there any way that

问题 I'm matching the indexPath with a pointer array against my data model to see which track is playing so that I can control audio playback using the didSelectItemAt delegate method. i.e. when a cell has been tapped it checks to see which song is playing based off the indexPath of the selected cell. (I am playing and pausing the audio within the didSelectItemAt delegate based off those parameters). I do this by switching a boolean in the pointer array for the track at the given indexPath. This

问题 I have a ListBox that uses a WrapPanel for its ItemsPanel , a custom ItemTemplate , and a custom ItemContainerStyle . The ItemContainerStyle's template contains a selection box that shows up when an item is selected. The graphics designer would like this selection box to overlap sibling items in the ListBox like it's an overlay. The first thing I tried was setting the Canvas.ZIndex property of the ItemContainer in the Selected state. That did not seem to have an effect. Then I read that list

问题 Write a program that prompts the user to enter a nxn matrix of double values and displays a new matrix which has the columns of the initial matrix sorted. You may use any sorting algorithm to solve the problem; please specify the name of the used sorting algorithm into your code header. Your program must implement a sorting algorithm; you cannot use the sorting methods provided in the Array class. The sorting should be implemented into a method, in which a new array is returned and the

问题 I'm trying to get the bounding box of a series of text selections stored in a list. The bounding box is the smallest rectangle that can contain the whole selection. Each item in the list has a start and end point measured in characters from the beginning of the QTextEdit window and also a letter identifier. QTextEdit.cursorRect(cursor) should do this, but is producing nonsensical box dimensions: id: A -- PySide.QtCore.QRect(0, 0, 1, 10) id: B -- PySide.QtCore.QRect(0, 0, 1, 10) id: C --

问题 I know it's similar to textview textIsSelectable="true" not working in Listview. Everything is fine when TextView is along, copy, parse. But when it's in list's item. I long click in Textview , The copy and parse menu seems appeal in top( ActionBar ), but it dismisses in half a second. I guess, the ListView is pushed down, so it's recall getView() . Ok, It's my guess. Can anyone helps me. My English is poor. If it's unclear, forgive me.... Thanks My getView: if (convertView == null) {

问题 I'm currently trying out C# and WPF for the first time. I have a window with two tabs, tabA and tabB .

On a certain event E , I want an item in listboxA or listboxB to be highlighted and selected, which one is determined by the logic in my application. Scenario A is that I am

问题 I have had this problem for a long time and I just can't figure out how to fix it. I want to create a simple WYSYWYG editor and I have some problems. Currently I have this: <div id="editor" contenteditable="true"></div> <input type="button" value="B" onmousedown="document.execCommand('bold',false,null); return false;"/> So, if I have some text inside my DIV, select it and click on "B" it is converted to BOLD, and remains selected, but this doesn't work on Opera and IE.
