window-resize

问题 In a Delphi 10.4 VCL Application, I need to detect when the FORM RESIZING ENDS . (E.g. after the user resized the Form by dragging its size-grip). So I have placed a TApplicationEvents component on the form and created its OnMessage event-handler, trying to catch the WM_EXITSIZEMOVE message: procedure TformMain.ApplicationEvents1Message(var Msg: tagMSG; var Handled: Boolean); begin if (Msg.Message = WM_EXITSIZEMOVE) then begin CodeSite.Send('TformMain.ApplicationEvents1Message: WM

问题 In a Tkinter GUI, during window resizing at runtime, I've noticed that the removal of a widget or a frame, using my_widget.destroy() , resets the window size to the original shape (the one it had at the start of the resizing). I've found an identical question HERE, with no solution. Couldn't find anything else online. Is there a way of calling a destroy without interrupting the resize action and resetting the size? Here is a sample code to test this behavior (creates an empty window of width

问题 I have a WinForm that is used to host a WebBrowser control. I want to dynamically resize the form based on the document size that the browser loads. I can successfully read the document size from within the WebBrowser control and I set the form size based on that, but the form simply will not resize. The resize is within the WebBrowsers DocumentCompleted event: private void ViewWebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { ViewWebBrowser.Height =

问题 Context from Kenny Kerr's blog: Windows Vista introduced a service called the Desktop Window Manager. The name was and continues to be misleading. Think of it as the Windows composition engine or compositor. This composition engine completely changed the way application windows are rendered on the desktop. Rather than allowing each window to render directly to the display, or display adapter, every window renders to an off-screen surface or buffer. The system allocates one such surface per

问题 When resizing down in DirectX I noticed a flicker along the bottom/right edges. If you fix the size of the swapchain (in red), and set the win32 background to green you will get the following on a resize down: It appears that the window size lags behind the mouse position ("Drag Rectangle") but the area DirectX fills (in red and black) matches the Drag Rectangle, with the remainder to be painted with the window background color (green). The DirectX Utility Toolkit (DXUT) didn't have this

问题 Current custom window(base) is: <Window x:Class="Views.DialogWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:Views" xmlns:dialog="clr-namespace:ViewModels" mc:Ignorable="d" Title="DialogWindow" Height="450" Width="800" WindowStartupLocation="CenterScreen"

问题 I'm playing with some responsive design that have two breakpoints defined: Mobile > max-width 320px Tablet portrait > max-width 767px On desktop I have a lot of animation + advanced functionality going on with Javascript. On mobile and tablet im looking to simplify and disable both some JS + "re-building" some DOM elements. Im wondering what the most efficient way to determine certain breakpoints (in terms of width) would be? Im thinking a lot about performance here. I know I can simply check
