button

问题 I have a button in my project that works like this: The button has 3 different designs for each state - disabled ( state_enabled="false" ), enabled, pressed. This button remains disabled if no file is selected, and has a particular design for it. Although, when file is selected, this button becomes enabled and switches to a different design. And the button's highlight color is possible to see every time when the button is enabled and pressed. What I have tried so far: <?xml version="1.0"

问题 I would like to be able to change the value of a parameter by clicking on a R shiny button. So I need to buttons, one for increasing and one for decreasing the value. I would like to keep the de-/increase of the value with a certain speed while holding the button. By releasing the click of the button the action should stop. So far I have not found this option for the actionButtons in R shiny. Is there another type of button which gives this opportunity? 来源： https://stackoverflow.com/questions

问题 Is it possible to enlarge the tiny check box of the Checkbutton object? The size is out of proportion when increasing the text size. I searched through the following link (Checkbutton) and can't find anything about the actual size of the box. Thank you for your help. 回答1: It is not possible to change the size of the checkbutton, but you can supply your own images. So, one solution is to create your own images at various sizes. 来源： https://stackoverflow.com/questions/46265567/how-to-increase
