Octave 如何创建uitab或uitab组

我想用八度音阶运行一些Matlab代码。 它调用uitabgroup（） 我已经寻找了一种八度音阶的方法来创建标签，但是没有用 我有fltk gnuplot和qt图形工具包可用

有人能帮忙吗

谢谢

出于兴趣，我试了一下。这里我展示了一个特定的示例，说明如何使用

uitabgroup

和

uitab

将简单代码转换为倍频程。这决不是一个通用的解决方案，但是如果您研究代码几分钟，就应该清楚地知道如何使其适应您自己的问题

主要思想是编写自己的

uitabgroup

和

uitab

函数，让它们在同一位置创建“按钮”而不是“选项卡标签”和“uipanels”，作为选项卡内容。按下每个按钮可使一个uipanel可见并隐藏所有其他uipanel

下面是比较结果：

目前似乎不支持此命令，但原则上用现有命令模拟其功能应该很简单，因为选项卡所做的是在按下“标题”按钮时有效地隐藏/取消隐藏位于相同坐标中的轴。如果您愿意，您可以使用uitoolbar或按钮组等。如果您确实愿意，您可以使其看起来完全像选项卡式界面。另一方面，如果你要问的是，是否有一个神奇的命令可以用最少的编辑来转换你的matlab UITABGOUP代码，那么可能没有。话虽如此，我认为可能有一个漂亮的替换涉及UITABGOUP->UIButtongGroup和uitab->uicontrol，这将起作用。。。
