expand

问题 I want to list all items that hippie-expand creates, then choose from them by moving the cursor and hitting RET. Is there any way to do this? 回答1: Here's what I'm using for this purpose: (global-set-key (kbd "M-i") 'complete-with-helm) (require 'ac-helm) (require 'auto-complete-config) (ac-config-default) (defun ac-complete-with-helm-auto () "Select `auto-complete' candidates by `helm'. It is useful to narrow candidates." (interactive) (let ((c (ac-candidates))) (if (= (length c) 1) (ac

问题 I have a NSOutlineView, and clicking on a row will expand/collapse the item if it's expandable. if ([self.outlineView isItemExpanded:item]) { NSLog("Will collapse item : %@", item); [[self.outlineView animator] collapseItem:item]; } else { [[self.outlineView animator] expandItem:item]; } Expanding the item works as expected, however collapsing the item is not working. I did get the log before executing collapseItem:, and the item is correct. The delegate method - (BOOL)outlineView:

问题 I have a datagrid with the itemsource bound to a ListCollectionView with one group.

问题 When a div has white-space: pre and has too much content, it will overflow the page, adding a scrollbar. How do I get the div to be as wide as it expands to? Example: http://jsfiddle.net/TkcTZ/1/ If you scroll to the right, you'll see that the background only extends to the right of the viewport, not past the edge behind the overflowing text. If you inspect the div with web tools, you will see that it is because the div is only as wide as the background. How do I make divs expand widthwise

问题 Please consider: Clear[x] expr = Sum[x^i, {i, 15}]^30; CoefficientList[expr, x]; // Timing Coefficient[Expand@expr, x, 234]; // Timing Coefficient[expr, x, 234]; // Timing {0.047, Null} {0.047, Null} {4.93, Null} Help states: Coefficient works whether or not expr is explicitly given in expanded form. Is there a reason why Coefficient needs to be so slow in the last case? 回答1: Coefficient will not expand unless it deems it absolutely necessary to do so. This does indeed avoid memory explosions

问题 I am looking for an efficient way to expand/collapse hierarchical table rows using jQuery. The problem is, that the expand and collapse functionality differs. Initially, only rows with class level_0 are show, all other rows are hidden. expand should only show the next level, so clicking on row id=10 should only make rows with id=11 and id=14 visible. collapse on the other hand, should collapse all consecutive rows with a deeper level than the current one. For example, clicking collapse on row

问题 I'm trying to add a sliding panel to my layout that is similar to sliding drawer, except that it will be placed to the left of my main layout and not overlaying it. There's a small button on the top left of my layout that expands/collapses the panel when I click on it. When it expands/collapses, I want the animation to be smooth so that the view that is adjacent to it will move as well. Here's the code I've tried. The panel stops working after the first expand/collapse: public Animation
