将扩展器(折叠/展开)添加到面板窗体

还有另一个WinForms扩展器: http://jfblier.wordpress.com/2011/02/16/window-form-expander/

这个 SplitContainer 控件可以折叠其两个面板中的一个。你可以在门上扣个钮扣 Panel1Collapsed

看看我的WinFormExpander控件- https://github.com/alexander-makarov/ExpandCollapsePanel

一般来说,它必须满足这种控制的所有基本要求。

• 在窗体设计器中轻松编辑
• 将所需的任何控件放入内容区域
• 应用不同的样式和大小

使用 SplitContainer 折叠是指:

Visible 属性来显示/隐藏它。这样,当空间不可见时,其他停靠的项目将移动以填充空间(取决于它们的位置) Dock

例如,如果隐藏面板时按钮、面板和标签都固定在顶部(按该顺序),则标签将上移到按钮下方。

我没法工作 (不记得细节了,但我遇到了麻烦) ,所以今天我直接用这个函数手动完成了。要折叠控件,请传递一个否定参数作为\u sz。

    /// <summary>
    /// (In|De)creases a height of the «control» and the window «form», and moves accordingly
    /// down or up elements in the «move_list». To decrease size pass a negative argument
    /// to «the_sz».
    /// Usually used to collapse (or expand) elements of a form, and to move controls of the
    /// «move_list» down to fill the appeared gap.
    /// </summary>
    /// <param name="control">control to collapse/expand</param>
    /// <param name="form">form to get resized accordingly after the size of a control
    /// changed (pass «null» if you don't want to)</param>
    /// <param name="move_list">A list of controls that should also be moved up or down to
    /// «the_sz» size (e.g. to fill a gap after the «control» collapsed)</param>
    /// <param name="the_sz">size to change the control, form, and the «move_list»</param>
    public static void ToggleControlY(Control control, Form form, List<Control> move_list, int the_sz)
    {
        //→ Change sz of ctrl
        control.Height += the_sz;
        //→ Change sz of Wind
        if (form != null)
            form.Height += the_sz;
        //*** We leaved a gap(or intersected with another controls) now!
        //→ So, move up/down a list of a controls
        foreach (Control ctrl in move_list)
        {
            Point loc = ctrl.Location;
            loc.Y += the_sz;
            ctrl.Location = loc;
        }
    }

我只是在groupBox上添加了一个标签,并将这个函数添加到标签的onClick事件中。为了让用户更清楚地了解扩展能力,我在文本的开头添加了字符 ⇘ .
