imagelist

问题 I have a ListView with View property set to LargeIcon . And I have an ImageList as image source for ListView . What I want is to display both vertically and horizontally oriented images in ListView but ImageList have only a single property ImageSize for all images in its collection so for example if I set that property to 150x100 and add a vertical image (100x150) to collection - ListView automatically stretches it to 150x100. So as I understand I need some ImageList , in which every image is

问题 At the moment I am getting items out of my database and add them to a string called result which I return and set to my TextView: protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.level); loadDataBase(); int level = Integer.parseInt(getIntent().getExtras().getString("level")); questions = new ArrayList<Question>(); questions = myDbHelper.getQuestionsLevel(level); tvQuestion = (TextView)

问题 I have a VB 6.0 application which contains some images inside a imagelist control. I want to know where these images get stored in the system.( because I want to use these images in another application and I dont have the images seperately in the system) So, the only way is to take the images from Visusal basic 6.0 project. Do we have anything like resource folder similar to .Net? Please let me know soon. Thanks Rupa 回答1: Start an empty project. Add reference (Ctrl+T) to Microsoft Windows

问题 I have an image list and would like to add a directory of images to the image list in my code. How would I do this? When I run the code: 'Load all of the items from the imagelist For Each path As String In Directory.GetFiles("Images\LanguageIcons\") imlLanguagesIcons.Images.Add(Image.FromFile(path)) Next I get an out of memory exception. Currently there is only 14 images so there really shouldn't be a problem. Any Help? 回答1: Like this imageList.Images.Add(someImage); Where someImage is an

问题 I'm trying to create and paint at runtime a 32 bit bitmap, and then add it to an ImageList. The bitmap has transparency (alpha-channel). I can create the bitmap and draw on it's Canvas with no problem, and it draws normaly with transparency over any other canvas. The problem is when I add it to an ImageList, the image seems to lose the drawings made with the Canvas property of the bitmap. Here is how I start the Bitmap: Bitmap := TBitmap.Create; Bitmap.PixelFormat := pf32bit; Bitmap

问题 I am having some problems utilizing an ImageList for my ListView in a .net application. In my implementation, this ImageList can hold a few thousand images depending on use. The issue originally arose when I was trying to work with a large number of images. Once I was getting past 5K+ images, I was running into a generic "Image cannot be added to the ImageList" exception trying to add an image. The exact number where this failure occurred jumped around a little bit. So, in trying to solve

问题 Here is (more or less) a related question: Delphi - Populate an imagelist with icons at runtime 'destroys' transparency. I have tested @TOndrej answer. But it seems I need to have visual styles (XP Manifest) enabled for this to work (version 6.0 of Windows common controls will be used - which I don't want right now). I add the Icons at run-time via ExtractIconEx and ImageList_AddIcon . Apparently setting ImageList.Handle to use System Image-List handle, does not require XP Manifest. so even

问题 I've spended hours for this (simple) one and don't find a solution :/ I'm using D7 and the TImageList. The ImageList is assigned to a toolbar. When I populate the ImageList at designtime, the icons (with partial transparency) are looking fine. But I need to populate it at runtime, and when I do this the icons are looking pretty shitty - complete loose of the partial transparency. I just tried to load the icons from a .res file - with the same result. I've tried third party image lists also

问题 I have a list of objects with a StreamedContent property and I need to show it in the <p:graphicImage> component. <ui:repeat value="#{testuser.answers}" var="imageanswers"> <p:graphicImage value="#{imageanswers.imageAnswer}" alt="Image" width="200" height="100" /> <br /> </ui:repeat> But this isn't shown. It displays the alt text instead. I saw this other post Use of p:graphicImage in ui:repeat or p:dataTable, but I don't understand the getImages() method. 回答1: I don´t get the getImages

问题 I've got the following image: I'm reading it from resources, putting into ImageList and then reading it from ImageList to draw on my control's surface. But when I'm doing that, image seems to loose information about alpha channel: Here are all relevant pieces of code: Program.cs Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); MainForm.cs ilFilters = new ImageList() { ColorDepth = ColorDepth.Depth32Bit, ImageSize = new Size(16, 16) }; // (...) if (info
