In my case for jQuery mobile they create a dialog box that overlays the page with all the options the user can select. <div data-role="fieldcontain"> <label for="select-choice-1" class="select">Choose shipping method:</label> <select name="select-choice-1" id="select-choice-1" multiple="multiple"> <option value="standard">Standard: 7 day</option> <option value="rush">Rush: 3 days</option>

Custom keyboard view in android

阅读更多关于 Custom keyboard view in android

I'm developing a custom Android keyboard. I started to develop my keyboard, based on this tutorial. However, I want my keyboard to have customized view instead of the default keyboard view. To be specific, I want to use listview to select words. Is this possible? Thanks in advance. You don't have to use the KeyboardView widget.. just put whatever views you want into the keyboard.xml layout file. I haven't tried using listviews, but I know that normal layouts/buttons/imageviews/textviews work fine. 来源： https://stackoverflow.com/questions/29285276/custom-keyboard-view-in-android

How to change the behavior of a python dictionary's setattr?

阅读更多关于 How to change the behavior of a python dictionary's __setattr__?

问题 In Python, everything has a class. Therefore dict also has a class. So, in theory, I should be able to change the implementation of the keyvalue assignment behavior. Example: d = dict() d['first'] = 3 # Internally d['first'] is stored as 6 [i.e. value*2 if value is INT] print d['first'] # should print 6 d['second'] = 4 print d['second'] # should print 8 I noticed that most objects have attributes listed in OBJECT.__dict__ or vars(OBJECT) . But this isn’t the case for dict or list . How can I
