如何在标题栏上增加按钮大家在使用某些软件的过程中，有没有注意到有些软件有一些很有趣的东西。

比如说在主窗口的标题栏上居然有一个按钮。

在Internet中随处可见这样的小控件。

按钮怎么可以加入到非客户区(Client)呢？在这里，最关键的一点就是，大家不要被传统知识误导：真的认为它是一个按钮。

有名柄（handle)的控件当然不能放在标题栏上了。

有经验的程序员用Spy++跟踪一下的话，马上就会发现其中的秘密。

它并不是一个按钮，只不过是处理成按钮的样子罢了。

既然知道了所以然，那么我们为什么不能自己来做一个呢，当然没问题，下面我们就用Delphi来实现它，讲注意我的注解。

在具体实例之前，我们应该知道几个关于标题栏的重要的消息：WM_NCPAINT：重画标题栏消息。

我们必须截住它，可以在这里重画按钮；WM_NCLBUTTONDOWN：在标题栏上按下鼠标左键消息。

我们可以截住它，在标题栏上画出按钮按下的样子，并且可以在其中进行自已的单击事件的处理，使得它像一个按钮；WM_NCLBUTTONUP：在标题栏上释放鼠标左键消息。

我们可以截住它，在标题栏上画出按钮弹起的样子；WM_NCLBUTTONDBLCLK：在标题栏上双击鼠标左键消息。

我们可以截住它，当在按钮区域双击时，我们就该使其无效，从而避免窗体执行最大化和还原操作。

WM_NCRBUTTONDOWN：在标题栏上按下鼠标右键消息。

我们可以截住它，当在按钮区域双击时，我们就该使其无效，从而避免弹出窗体按制菜单。

WM_NCMOUSEMOVE：在标题栏上移动鼠标消息。

我们可以截住它，当鼠标移出按钮区域时，我们就必须画出按钮没有被按下，即凸起时的样子。

WM_NCACTIVATE：当标题栏在激活与非激活之间切换时收到该消息。

我们可以截住它，当该窗口处理激活状态时，我们可以做一些事情，比如说将我们的标题栏按钮上的字体变灰或变黑来指示该窗口的当前状态。

下面我没有加入该项功能，如果大家感兴趣的话，可以自己完成。

Delphi界面设计专辑［前言:］界面的美观和用户亲和性是应用软件成功的首要条件,因此界面往往是程序员最费心的地方。

在这个专辑中,将向读者全面介绍Delphi中界面设计的原则和技巧窗体设计制作固定大小的Form固定的Form像一个对话框,何不试试下面的语句巧用Delphi制作溅射屏幕精心编写的WINDOWS程序显示启动注意事项,称之为溅射屏幕(splash screen)。

利用一点儿小小的内容,即可给程序的显示添加不少色彩LED数码管仿真显示程序在电子设备上广泛地使用LED数码管显示数据,在许多应用软件中也经常模拟LED数码管显示数据,使程序画面看起来很有特色菜单设计DELPHI中自适应表单的实现我们知道,屏幕分辨率的设置影响着表单布局,假设你的机器上屏幕分辨率是800*600,而最终要分发应用的机器分辨率为640*480,或1024*768,这样你原先设计的表单在新机器上势必会走样作非常规程序菜单掌握delphi高级秘籍大家可能见过诸如金山毒霸,瑞星杀毒,以及五笔输入法等等在系统托盘(即右下角有时间和输入法图标的地方)在的控制菜单,而在正常的任务栏(即屏幕最下方的“开始”按钮的右边的各式各样)中却不出现按钮的程序,即我们常说的在后台运行的程序用Delphi制作动态菜单所谓动态菜单是指菜单项随着程序的操作变化而变化。

现在,我们用Delphi来实现这一功能,具体步骤如下工具栏和状态条为Windows窗口标题栏添加新按钮对于我们熟悉的标准windows窗口来讲,标题栏上一般包含有3个按钮,即最大化按钮,最小化按钮和关闭按钮。

你想不想在Windows的窗口标题栏上添加一个新的自定义按钮用Delphi4实现风Word97格的工具栏用过Word97的人对它的工具栏印象很深刻,因为它的风格很“酷”,同样IE4.0的工具栏也有类似的风格,Win98的出现,使这种风格的工具栏得到了推广如何隐藏和显示Windows的任务条如果隐藏和显示Windows的任务条?仅仅调用以下的函数就可以.其他技巧Delphi利用Windows GDI实现文字倾斜在Delphi开发环境中,文字的输出效果一般都是头上脚下的"正统"字符,如何输出带有一定倾斜角度的文字以达到特殊的显示效果呢Delphi之三十六计之界面篇设置状态栏面板对象的Style为OwnerDraw,并在状态栏对象的DrawPanel事件中书写以下代码利用COM技术实现外壳扩展的属性页当用户在资源管理器中调用右键菜单时,会显示一个"属性"菜单项,点击属性菜单项会显示一个属性页,用户可以获得甚至修改文件信息制作固定大小的Form固定的Form像一个对话框,何不试试下面的语句？C++ Builder请参照Delphi的例子Delphi您可以覆写CreateParams() 这个TWinControl 的虚拟程序, 改变form的wc.Stylee, 将WS_SYSMENU 这个旗标解除, 这样, 就不会有左上角的SystemMenuBox 了.至於不能移动.缩小/放大, 可以自已拦下WM_NCHITTEST, 然後一概回应滑鼠点在视窗Client 区域, 相信这个视窗就呆呆的不会动了.详情可以查一下Win32API Help 的CreateWindow() 与WM_NCHITTEST 的说明.unit Unit1;interfaceusesWindows, Messages, SysUtils, Classes, Graphics, Controls,Forms, Dialogs, StdCtrls;typeTForm1 = class(TForm)Button1: TButton;procedure Button1Click(Sender: TObject);private{ Private declarations }procedure WMNCHitTest(var Msg: TMessage); message WM_NCHITTEST;protectedprocedure CreateParams(var Params: TCreateParams); override;public{ Public declarations }end;varForm1: TForm1;implementation{$R *.DFM}巧用Delphi制作溅射屏幕精心编写的WINDOWS程序显示启动注意事项,称之为溅射屏幕(splash screen)。
