wxPython 使面板无法通过选项卡访问 [英] wxPython making a panel not accessible through tab

问题描述

我使用 wx.glade 构建了一个 gui.此 gui 的一部分是输入密码然后单击按钮以验证它们的部分.为了制作这个部分，我使用了一个网格大小器.并非网格的每个单元格都需要有一个按钮或字段，所以我用 wx.panel 组件填充它们作为间隔.

I built a gui using wx.glade. Part of this gui is a section to enter in passwords and then click a button to validate them. To make this section I used a grid sizer. Not every cell of the grid needed to have a button or field in it, so I filled these with wx.panel components as spacers.

发生的情况是，当我在 tx 字段和按钮中使用 Tab 键时一切正常，但 wx.panel 间隔符也是该选项卡列表的一部分.我想要做的是使它们不可选择.

What happens is that as I tab through the tx fields and buttons everything is fine, but the wx.panel spacers are also part of that tab list. What I want to do is make them non-tab selectable.

推荐答案

面板本身通常不接受焦点，所以这有点奇怪.您可以捕获焦点事件并告诉它将焦点设置在下一个小部件上，假设您自己跟踪 Tab 键顺序.或者您可以尝试禁用面板，这应该具有相同的效果.

Panels usually don't accept focus per se, so that's a little odd. You can catch the focus event and tell it to set focus on the next widget instead, assuming you keep track of tab order yourself. Or you can try disabling the panels, which should have the same effect.
