WINDOWS API COPYIMAGE WINDOWS
Might have a memory leak and bug or two, parts of it are not being used, etc.īut then it just works, simple, elegant.shows you a Windows XP looking window frame on what ever Windows OS you run it on, regardless of your theme or performance settings. It kind of looks like this was a working prototype, and, or some rough cut and paste from some larger project. It's still a gem and really helped me as a launching point to get my own custom window frames going. Like the title says "Win32 API", any other examples I could find were using MFC, or some other bloated GUI framework. Out of the all the web searching back then and still now it's one of the, if not the, best working examples around. Here it is 2014 as I write this but I remember downloading this years ago and finally getting around to using it.
WINDOWS API COPYIMAGE CODE
There will be bugs and errors! I hope that you find this code useful. I wanted something similar to SkinWindow in functionality, but without the overhead of MFC.
WINDOWS API COPYIMAGE HOW TO
I want to tell a beginner how to skin a window using pure Win32 API without MFC and give the beginner some hints to comprehensive window messages. This is by no means a finished product! This is my first attempt at writing a terribly complicated Win32 application library. Is there anyone who can resolve it? The problem's picture is like below. I've tried many approaches, but the problem persists. When you size or drag and move a window as fast as you can, the monitor will flash and the window will take up more CPU percent. Return SkinWin.WndProc( hWnd, message, wParam, lParam ) Problems/Bugs If( SkinWin.IsHandledMessage( message ) ) Functionįirstly, we create a new Win32 application that includes SkinWindow in its project.Ĭopy Code // handle some special window's message here The class SkinWindow defines some functions to process the special window's message. We should create a class named SkinWindow that takes responsibility for painting the window. If the windows use different input queues, the message is sent asynchronously, so the window is activated immediately. First it is sent to the window procedure of the top-level window being deactivated and then it is sent to the window procedure of the top-level window being activated. If the windows use the same input queue, the message is sent synchronously. The message is sent to both the window being activated and the window being deactivated. An application can use this message to override the window's default maximized size and position, or its default minimum or maximum tracking size. The message is sent to a window when the size or position of the window is about to change. If a window has captured the mouse, this message is not posted. This message is posted to the window that contains the cursor. The message is posted when the user releases the left mouse button while the cursor is within the non-client area of the window.

If the mouse is not captured, the message is sent to the window beneath the cursor.

The message is sent to a window when the cursor moves or when a mouse button is pressed or released. The message is sent to a window when its non-client area needs to be changed to indicate an active or inactive state.

By processing this message, an application can control the content of the window's client area when the size or position of the window changes. The message is sent when the size and position of a window's client area must be calculated. The message is sent to a window when its frame must be painted. Anybody who wants to draw a window should process the window messages as below: Message The Problems Existing in the SkinWindow Classįor the beginner, I want to explain the window messages that should be processed.How can you make an application's own skin window without MFC extension UI libraries like BGCControlBar, Xtreme Toolkit and so on? This article uses pure Win32 API to find the answer.
