That turned out to be easier than I thought. Simply adding this row makes the selection to be by row instead of cell. self.tv.setSelectionBehavior(QAbstractItemView.SelectRows)
dataGridView1.ClearSelection(); Should work. Maybe you have code that auto selects rows which is triggered?
The first one gets the reference and checks if the element exists, and saves this status as a boolean value in the variable. If the element exists, the variable contains true otherwise false. You would use the first one if you only want to know if the element exists, but don’t need the reference to … Read more
Not perfect but it’s working: http://jsfiddle.net/coma/9p2CT/ Remove the real selection ::selection { background-color: transparent; } Add some styles span.highlight { background: #ADD6FF; } span.begin { border-top-left-radius: 5px; border-bottom-left-radius: 5px; } span.end { border-top-right-radius: 5px; border-bottom-right-radius: 5px; } pre.merge-end > span:last-child { border-bottom-right-radius: 0; } pre.merge-end + pre > span:last-child { border-top-right-radius: 0; } pre.merge-begin > … Read more
Handle the mousedown-event instead of the click-event. The mousedown event will be handled before the focus of another element is lost. In your mousedown eventhandler, you need to to prevent event default behavior. e.preventDefault(); // in your mousedown eventhandler JS-Fiddle demo
So, how to get the string of the html of a Range or DocFrag? Contrary to the other responses, it is possible to directly turn a DocumentFragment object into a DOMString using the XMLSerializer.prototype.serializeToString method described at https://w3c.github.io/DOM-Parsing/#the-xmlserializer-interface. To get the DOMString of a Range object, simply convert it to a DocumentFragment using either of … Read more
The following will return the container element of the start or end boundary of the current selection, using the boolean isStart to specify whether you want the start or end boundary. It will work in most mainstream browsers. Add feature tests for more robustness. function getSelectionBoundaryElement(isStart) { var range, sel, container; if (document.selection) { range … Read more
Try this, it returns the selected text, no matter if it’s contentEditable or not. function GetSelectedText() { if (document.getSelection) { // all browsers, except IE before version 9 var sel = document.getSelection(); // sel is a string in Firefox and Opera, // and a selectionRange object in Google Chrome, Safari and IE from version 9 … Read more
I’ve done this in an interview before, and one of the most elegant/efficient ways to do this is O(n log k). with space: O(k) (thanks, @Nzbuu) Basically you’re going to use a max-heap of size limited to k. For each item in the array, check to see if it’s smaller than the max (only O(1)). … Read more
Disclaimer: I don’t know how std::nth_element is implemented in any standard library. If you know how Quicksort works, you can easily modify it to do what is needed for this algorithm. The basic idea of Quicksort is that in each step, you partition the array into two parts such that all elements less than the … Read more
