中央按钮软键LWUIT [英] Central Button Soft key LWUIT

问题描述

这似乎是一个非常琐碎的问题，但是我花了很多时间在此问题上，没有找到可行的解决方案.

This might seem like a very trivial problem but I have spent quite some time on this without finding a viable solution.

诺基亚设备具有中央选择按钮，可让我们为其分配软键.

Nokia devices have a central select button,which allows us to assign soft keys to it.

根据我的要求，我需要分配一个特定的命令作为软键.例如，在一个屏幕上可能是播放"，而在另一屏幕上可能是选择".请注意，我已经使用以下命令设置了默认选择命令:

According to my requirement, I need to assign a specific command as the soft key. For instance it might be "Play" on one screen and "Select" on other. Note that I have a default select command already set using:

setDefaultCommand((Command) v.elementAt(v.size() - 1));

它始终是右侧菜单中的第一个命令，并在按下中央选择按钮时被调用.

which is always the first command in the menu at the right and is invoked when central select button is pressed.

据我了解，将命令分配给每个软键的方式非常随意，并且因设备而异.由于已经设置了默认命令，因此可以通过两种方式解决我的问题:

From what I read, the way commands are assigned to each soft key is very arbitrary and varies from device to device. Since I have a default command already set, my problem can be solved in two ways:

1.通过使用中心按钮设置软键

1.By setting a soft key to the central button using

Display.getInstance().setThirdSoftButton(true);

我尝试过这种方法，但是分配命令的方式是非常随机的.另外，菜单中始终会添加一个默认命令选择".有没有一种方法可以对此进行自定义，以便在中央按钮上方显示一个非常具体的命令?

I tried this, but the way commands are assigned is very random. Also,there is a default command "Select" always added to the menu. Is there a way to customize this so that a very specific command is shown above the central button?

2.只需分配标签，即可在中央软键中显示如上设置的默认命令.

2.By just assigning a label so that the default command set as above is displayed in the central soft key.

推荐答案

第3个软键模式具有许多可聚焦组件的默认实现，但没有标签的实现.您可以通过在组件上调用setSelectCommandText(String)来自定义其标签.

The 3rd softbutton mode has default implementations for many focusable components but not for labels. You can customize its label by invoking setSelectCommandText(String) on the component.

我建议不要在中心命令中使用标签，而是使用一个按钮，并将其UIID设置为Label(如果希望它作为标准标签显示).

I suggest that rather than using a label for a center command just use a button and set it's UIID to Label if you want it to appear as a standard label.
