button

问题 I am using Python 3 with gobject introspection for Gtk. How can I have more than one toggle button linked together so they behave similar to tabs or radiobuttons - e.g. one is selected by default, and when another is clicked the previously active one is de-selected. I have tried using set_sensetive , but that greys out the widget that it is applied on. 回答1: Use set_active() (or props.active ). Alternatively, you can create some Gtk.RadioButton widgets and set draw_indicator property to False

问题 Can someone help me with a softkeyboard enter key listener? I need a enter key listener like a button listener that would have a few editext listeners inside like this enterkey.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if(editext1.getText().toString().equalsIgnoreCase("test1")) { button3.performClick(); } if(editext1.getText().toString().equalsIgnoreCase("test2")) { button4.performClick(); } } ); I also need something like below is this correct?

问题 Hi I am trying to code a simple application with Pygame. I have made various searches and found that best way to get an user input is to use a 3rd Party GUI. I have found Simple Game Code for this aim. Below, you can find my base code, it looks for the images inside same path of script and replaces them in order at screen. But I have no experience with this kind of applications. I am trying to understand from the documentation of SGC: https://github.com/codetricity/sgc/blob/master/example

问题 I have a dynamically generated form with groups of checkboxes representing categories of companies. These eventually get plotted on a dynamic chart (not shown here). Each group of companies has a toggle button to turn all the checkboxes on or off in each category. I have a jQuery handler for the first toggle button (Tech Giants) using its ID and then checks or unchecks all the boxes in that group accordingly. My question is this, which refers to the last portion of code in the block below.

问题 for my board game, I need to press a certain button and after that, disable it (to prevent the user or the computer to place a "peace" in the same place). The problem I have with this is basically design-wise: as you would know, when a button is disabled in tkinter, it turns grayed-out, kinda "visually blocking" the piece I placed... Here is an image of what I'm talking about: My question is, how would I disable a button, but keep it as if it wasn't disabled? I searched and the only answer I

问题 I want to create a custom button. This button should have a gradient and a two pixel border, but the inner and outer edge should be in a different color (example: inner is red and outer is yellow). My question: how do I program the double border (like in the image)?! Image: I tried with an XML file with two strokes, but it doesn't work. I could do this with a 9png file, but I want to do it with pure coding. 回答1: btn_bg.xml <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http

问题 I wish to add a 'trash' image on the top-right side of each button when 'Delete Button' is pressed, so that when user hits the trash image, the button will be removed from the vstack. I think I should use zstack to position the trash image but I don't know how for now. Below shows where the trash image should be located in each button. Also, when I press the 'Delete Button', it seems that each button's text size and spacing with another button is changed slightly. How do I overcome this
