button

问题 My buttons seem stretched, especially in landscape orientation. I can't find a property to adjust either on the UITabBar, UITabBarViewController, or on the UITabBarItem's themselves. (Of course, one answer would be to get an iPad...but that doesn't solve the need for a phone.) For example, consider this simple Tab Bar Example - if I only could set the tab bar to auto-shrink as more buttons are added, or manually adjust the width to fit them all on the tab bar, I would be happy. 回答1: It is not

问题 I have a button and when it's clicked, I want to replace the button with an image. How can I do this in JQuery? Is it possible to replace the background of the image as well?

问题 I'm developing an iPhone app that requires buttons to be of shapes other than rectangles/squares for eg, an amoeba shaped button. Also, when the button is clicked, the button is highlighted only as much as its size. So just setting a background image only is not enough. How should I go about it? 回答1: One way would be to make pre-rendered images for both the normal state and selected state. Then set use setBackgroundImage: forState: to set each image to it's appropriate state. I should add,

问题 I am trying to create a class called LinkButton, which is a simple class that loads a URL on a click (im doing this to simpify my designers' transition to AS3) . Even though I am importing the button definition, the AS file gets a compile error: 1046: Type was not found or was not a compile-time constant: Button. and 1172: Definition fl.controls:Button could not be found. I created the button by making a simple shape converting it to a symbol (F8) of type 'Button'. In my FLA file i have this

问题 I need help in linking a pushButton on my PyQt5 code so that it runs another .py file automatically. I have tried using 'self.pushButton.clicked.connect' but this does not seem to work on PyQt5 code.

问题 I've read plenty of answers that use the value of submit type input, but my collection of input buttons need to all have the same text. Others use Javascript, and I'm trying to avoid that as well. <input type="submit" value="Press This" name="submitButton" /> Doesn't work because they all need to be named 'Press This'. <button type="submit" value="12" name="submitButton">Press This</button> Doesn't work because it doesn't post the value. Is there some way to make the <button> submit it's
