Java的按钮宽度 [英] Java Button Width
问题描述
我试过使用此并不起作用。
singleplayerButton.setBounds（20，20，200，100）;
我不知道为什么，虽然，任何人可以帮助我这个？

我尝试完成使按键更小，所以不触及页面的一面。
我个人使用，会给你更多的灵活性，决定按钮的布局方式，使一个巨大的努力满足您的组件$ P $的布局管理器pferred大小，但给你自由作出调整，因为你需要...
对于我来说，这是的GridBagLayout

在这里，我使用 看一看 有关更多信息 I've tried to use this and it doesn't work I dont know why though, can anybody help me out with this? My full page code is here im trying to accomplish making the buttons smaller, so not touching the side of the page. I personally would use a layout manager that will give you more flexibility in deciding how the buttons are laid out and makes a great effort to honor your components preferred size, but gives you the freedom to make adjustments to as you need... For me, that's Here, I've used Have a look at For more information 这篇关于Java的按钮宽度的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！ ipadx 和 ipady 的的GridBagConstraints 通过布局管理器，以增加组件的宽度和高度，以及使用水平填以使所有的组件相同的宽度。singleplayerButton.setBounds(20, 20, 200, 100);

ipadx and ipady of the GridBagConstraints to increase the width and height of the components through the layout manager, as well as using the HORIZONTAL fill to make all the components the same width.
