visible

I would like to determine if a rect inside a window is completly visible. I have found RectVisible, but that function determines if any part of the rect is visible, I want to know if the entire rect is visible. Is there any function for this? First get the system clipping region (the visible region of a window) into a region by using GetRandomRgn . Read more about the 'system region' here . Then, offset that region since it is in screen coordinates (the article I linked has an example). After that, create a region from your rectangle with CreateRectRgn and combine the parts of your 'rectangle

How can I make a programmatical page selection visible to the user, as if it was selected by the user? var range = document.createRange(); var startPar = [some node]; var endLi = [some other node]; range.setStart(startPar,13); range.setEnd(endLi,17); Thank you. Use: window.getSelection().addRange(range); 来源： https://stackoverflow.com/questions/1426634/make-programmatic-range-selection-visible-to-the-user

I have this simple html markup generated from classic asp: <table> <tr class="trClass"> <td>Hello </td> </tr> <tr class ="trClass"> <td>World!</td> </tr> </table> If i set the tr belonging to Hello to hide() using Jquery it hides. Good! But, when i use this $('.trClass:visible').each(function() { alert('visible') }); it shows the output 'visible' twice. Why is this? My problem here is that im filtering a table on a column with a selection box. But after filtering i need to perform some calculations on those rows that are visible in the table, but i get all rows right now. Any ideas? /Daniel

需要导入这个js： import { GUI } from '/three.js/jsm/libs/dat.gui.module.js'; 局部代码： var params = { color: 0xffffff, transparency: 0.90, envMapIntensity: 1, lightIntensity: 1, exposure: 1, visible:true }; var gui = new GUI(); gui.addColor(params, 'color') .onChange(function () { material.color.set(params.color); }); gui.add(params, 'transparency', 0, 1) .onChange(function () { material.transparent = true;//允许透明 material.opacity = params.transparency;//设置 透明度 //material.transparency = params.transparency; }); gui.add(params, 'envMapIntensity', 0, 1) .name('envMap intensity') .onChange(function () {

I'm trying to toggle the display of a small window based on the click of a notify icon in a system tray app. This is simple enough to implement, however when the small window is displayed and another application takes focus and therefore moves in front of it (z-order) I want the toggle to assume that the small window is now hidden, even though it's visibility is still set to visible. Otherwise, clicking the icon would set the windows visiblity to hidden even though it is already hidden behind another. I've tried catching / overriding the activate and deactive methods to keep track but clicking

If you set the Visible property of a Windows Forms control to true, that property still returns false if any of the control's parent windows are hidden. Is there a way to get the true, underlying visibility flag of the control in case the parent window is hidden? Marc Gravell Well, the regular implementation does check up the control stack, to ensure that all parents are visible. The only way I know to dodge this is to cheat with reflection, and ask for GetState(2) , but that is brittle: // dodgy; not recommended Panel query; Form form = new Form { Controls = { new Panel { Visible = false,

I have a class called Book; class Book { public string Name { get; set; } public string Author { get; set; } public int PagesCount { get; set; } public int Category { get; set; } } The ListBox displays a list of Books and the ItemTemplate has been modified so as to visually represent the Book. The text shows the book's Name, author and the number of pages. The category, however is represented by a certain color (for example, history is blue, romance is red etc.) Now, the text has an OuterGlowBitmap Effect and a value converter from the Category (int) to the appropriate Color. Everything is
