expand

问题 I used the code from question Wpf treeview - i want to animate the expansion of the nodes, but the animation doesn't work on the first expand, it does work for the consequent expand events. any ideas? 回答1: Change the Trigger Value to false and swap the EnterAction's storyboard to ExitAction's 回答2: Here is a solution: <Style x:Key="TreeViewItemStyle1" TargetType="{x:Type TreeViewItem}"> <Setter Property="Background" Value="Transparent"/> <Setter Property="BorderBrush" Value="Transparent"/>

问题 I am expanding and collapsing table view using plist value from one git hub tutorial. In that tutorial when i press row it is expanding, when i press the same row it is again collapsing no problem in that.

This is the code for expanding and collapsing - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [tableView

问题 I have to flatted a 3d array in order to be serialized. Let's start with this: int[,,] array3D = new int[,,] { { { 1, 2 }, { 3, 4 }, {5,6 }, {7,8 } }, { { 9, 10}, { 11, 12},{ 13,14} , {15,16 }}, { { 17, 18}, { 19, 20},{ 21,22}, {23,24 } } }; which makes it like this (something like 1,2,3,4,...,24): So now I have this s/r public static T[] Flatten<T>(T[,,] arr) { int rows0 = arr.GetLength(0); int rows1 = arr.GetLength(1); int rows2 = arr.GetLength(2); T[] arrFlattened = new T[rows0 * rows1*

问题 I'm about 2 months new to programming and Twitter Bootstrap, so please be kind! I've done a lot of digging and searching, but am not sure I am using the correct terms so I figure I'd ask directly. I am trying to create an Expand/Collapse all button that will expand or collapse all items under a Title Header. The items under a title header include a text piece and an image. I want to be able to expand/collapse the text piece by clicking on the Title Header. I want to be able to expand/collapse

问题 I'm attempting to switch from Vim to Emacs, but I'm tearing my hair out trying to configure it to treat tabs how I wish. I require: Inserted "tabs" to be expanded into two spaces. Emacs stubbornly sticks to eight, no matter what I do. Tabs (i.e. real \t characters) to be represented on screen by two spaces. Pressing TAB should insert a tab at the cursor rather than indent the entire line . Currently, I press TAB anywhere and Emacs destroys all whitespace at the start of the line; this is the

问题 Often in Matlab we would plot a figure with many subplot axes, but they are all tiny. In the prevalent UX paradigm, you would expect to be able to double-click such a small plot to have a closer look using the entire screen space. Typically this is the reason I avoid using subplot , but plot many individual figures instead — so I can move them around on the screen and double-click on their titlebars which (on Windows) maximises the figure to full screen. (Double-click again, and it returns to

问题 I have a big iOS-project with many folders / groups. When I quit and restart Xcode, all folders in the Project Navigator are shown expanded, so I have to collapse most of them manually. Is it possible to save the state of the Project Navigator , so that when Xcode restarts the same folders are collapsed / expanded as before? 回答1: The solution was to delete this file: MyProjectName.xcodeproj > project.xcworkspace > xcuserdata > myusername.xcuserdatad > UserInterfaceState.xcuserstate This file

问题 Is there a way to expand the Java memory-mapped byte buffer such that the new size is reflected back to the mapped file on disk? 回答1: No, you will need to adjust the size of the underlying file and recreate the Memory Mapped Byte Buffer. RandomAccessFile file = new RandomAccessFile(/* some file */); MappedByteBuffer buffer = file.getChannel().map(MapMode.READ_WRITE, 0, file.length()); // Some stuff happens... // adjust the size file.setLength(newLength); // recreate the memory mapped buffer

问题 I have a table at the top of my sheet and this table has a different section names. I'd like to insert a hyperlink to these section names to go and open it's group below when I click them. Please Refer to the view of my table and sections as default (Collapsed) I could create a macro which: Expands all groups Goes to the Section that I clicked, Collapses all groups Only opens the group on active cell, But assigning this macro to ~20 different sections increases the file size.
