Seems to work OK for me. With the lack of a full code example I’m assuming you’ve got your compositing mode wrong. public void RenderGdiPlus() { List<string> colors = new List<string>(new string[] { “000000”, “ff0000”, “00ff00”, “0000ff”, “ffffff” }); List<string> alphas = new List<string>(new string[] { “00”, “01”, “40”, “80”, “c0”, “fe”, “ff” }); Bitmap … Read more
Color fillColor = Color.FromArgb(0, 0, 0, 0); //(a, r, g, b) e.Graphics.FillRectangle(new SolidBrush(fillColor), e.ClipRectangle); This is actually rather amusing. It means that you are drawing something completely transparent – so this changes absolutely nothing! 🙂 Guess: if black (0,0,0) should mean “glass”, how about drawing (1,1,1) to get (almost) black?
It seems to work if you put the Style as a lower-level resource, instead of in the same ResourceDictionary: <Grid xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”> <Grid.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source=”/PresentationFramework.Aero, Version=3.0.0.0, Culture=Neutral, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=MSIL;component/themes/aero.normalcolor.xaml”/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Grid.Resources> <Border BorderBrush=”Blue” BorderThickness=”3″> <Border.Resources> <Style TargetType=”{x:Type TextBox}” BasedOn=”{StaticResource {x:Type TextBox}}”> <Setter Property=”Margin” Value=”2″ /> <Setter Property=”Padding” Value=”2″ /> </Style> </Border.Resources> <TextBox … Read more
Since GDI forms on Delphi don’t support alpha channels (unless using alpha layered windows, which might not be suitable), commonly the black color will be taken as the transparent one, unless the component supports alpha channels. tl;dr Just use your TTransparentCanvas class, .Rectangle(0,0,Width+1,Height+1,222), using the color obtained with DwmGetColorizationColor that you could blend with a … Read more
After using Spy++ to inspect Steam’s window (its window styles, how it replies to window messages) and trying to match everything it does, combined with the DWMAPI calls from this C# borderless window behavior, I believe I figured it out. To hide the window’s border, handle the WM_NCCALCSIZE message in your WindowProc: case WM_NCCALCSIZE: { … Read more
Skype cheats it, and has a little sliver along the top of their window; where they can draw it. You can see it with Process Explorer to SpyXX: See also MSDN: Custom Window Frame Using DWM
Here is a version with much less flickering, still not perfect though. public class GlassControlRenderer : NativeWindow { private Control Control; private Bitmap Bitmap; private Graphics ControlGraphics; private object Lock = new object(); protected override void WndProc(ref Message m) { switch (m.Msg) { case 0x14: // WM_ERASEBKGND this.CustomPaint(); break; case 0x0F: // WM_PAINT case 0x85: … Read more
Colorization color != the base color chosen. It’s misleading, I know. But I’m confused. The image you borrowed was from my post entitled “Retrieving Aero Glass base color for opaque surface rendering”. Is this not what you want to do? I also indicated in the post the registry location in which all the color information … Read more
