tabcontrol

问题 I'm new to Delphi (again - I used Delphi back in 1994). I now have Delphi 2009 Pro. Coming from Java, I find the object inheritance very obscure. My users want tabbed pages with the tabs on the left. But, the TPageControl doesn't allow the tab label direction or orientation to be changed. They want the words on the tabs to read top to bottom with the letters rotated so they are in a "normal" orientation. With the tabs on the left the labels read from the bottom up with the letters rotated 90

问题 How can I make a transparent tabPage? I found solutions like set both Form's BackColor and TransparencyKey to a color like Color.LimeGreen or override OnPaintBackground with a empty method but TabPage doesn't have neither TransparencyKey property nor OnPaintBackground` method. How can I do that? 回答1: TabControl is a native Windows component, it always draws the tab pages opaque with no built-in support for transparency. Solving this requires a little helping of out-of-the-box thinking, a tab

问题 In the project I am building I have a TabControl in which I want to display a range of tabs through an ItemsSource . I also need to have a few "overview" tabs at the beginning of the TabControl , that cannot be located in ItemsSource . What is the best way to achieve this, the only way I can think of is to have my overview tabs in my XAML and to just add tab items manually through code instead of using ItemSource is this the best way to go about it. 回答1: You can use CompositeCollection (MSDN)
