c control gets focusCan the c control gain focus even if it is hidden?

C control hiding and focus acquisition

When a C control (for example: button, text box) is hidden, it usually loses focus because the user cannot interact with the invisible control. However, whether a control can gain focus depends on the specific implementation and circumstances. Different development frameworks and platforms may handle this differently, some may retain focus, while others may automatically transfer focus to visible controls. Therefore, in the specific development process, it needs to be handled according to the actual situation.

Case 1: The control is hidden or loses focus.

When a control is explicitly hidden, it usually loses focus automatically. This is because focus refers to the control the user is currently interacting with, and if the control is not visible, the user cannot interact with it. Here is the sample code:

CButton myButton;
myButton.ShowWindow(SW_HIDE); // 隐藏按钮

In this case, the hidden button will lose focus and the user will not be able to click on it.

Case 2: Although the control is invisible, it can still get focus.

Sometimes you may want a control to still gain focus when it is invisible so that you can interact with it when it reappears later. This can be accomplished by setting the control's WS_TABSTOP style to TRUE to ensure that it is included in the tab key's focus traversal. The sample code is as follows:

CButton myButton;
myButton.ModifyStyle(0, WS_TABSTOP, 0);
myButton.ShowWindow(SW_HIDE); // 隐藏按钮,但仍然可以获取焦点

In this case, although the button is hidden, you can still set the focus by pressing the Tab key, and then you can simulate actions such as button clicks by pressing the Enter key.

Summary

Normally, when a C control is hidden, it loses focus because the user cannot interact with the invisible control. However, by styling the control appropriately, you can make it invisible and still gain focus so that you can interact with it later. It depends on your specific needs and implementation, and you can achieve this by setting the focus state of the control as needed.
