customization

问题 I use the IPython 2.0 Notebook for teaching. The notebooks are created before the teaching session, and used as-is during the session. Sure, when I prepare the notebook, it has sense that I access all the cells in sequence (actually, I don't). Back in class, while I present the concepts and the code to the students, I don't need the focus to be put on the next cell, I just need the cursor to wait in the next code cell... The best I can hope is that someone has been able to change the default

问题 Has anybody succeeded in customizing the Places Bar for VS 2008? My customizations from VS 2005 did not transfer to 2008 (obviously), and no matter what I do with the registry, I cannot make my custom places appear on the Open dialogs. I have read and applied the relevant MS KB article, to no avail. This used to work fine with VS 2005, so it may well be a VS 2008 bug, but I may be wrong trying the same approach. 回答1: some observations: VS2008 uses now Common File Dialog. With Powertoys

问题 I am trying to make a special kind of jtable. I want the entire table to by default be NOT editable. But when the user clicks a row, then clicks the "Edit" jbutton, that specific row is editable. and once they deslect the row its no longer editable. How would I go about doing this? 回答1: to control which cells are editable, you will need to extend either JTable or JTableModel (see the call to the model in the example below) to ensure that this method from JTable returns true for all the cells

问题 I'm trying for hours to make a left button work properly and mimic a back button. My code to create the button: UIBarButtonItem *backButton = [self customBarButton:@"back_button" imageHiglighted:@"settings_button_highlighted" x:20 y:0 widthDivider:2.6 heightDivider:2.6]; backButton.target = self; backButton.action = @selector(buttonPressed:); self.navigationItem.leftBarButtonItem = backButton; Here the method called to create custom button: - (UIBarButtonItem *)customBarButton:(NSString *

问题 I have a customized UISlider which has its track image disappear sometimes. It happens at random and when its parent view controller is pushed to visible (I never see it actually disappear). Here is my code for setting up the UISlider: timeSlider = [[UISlider alloc] initWithFrame:CGRectMake(55, 8, 210, 23)]; timeSlider.backgroundColor = [UIColor clearColor]; UIImage *blutrackImg = [[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"bluetrack" ofType:@"png"]];

问题 I'm using a couple of PopupMenu s in my app and they all working as expected But I would like to have white lines separating the individual items, but I can't find where I'm meant to be setting this. I was hoping I could get to the underlying ListView but that doesn't seem to be possible. I can't see an style item that relates to the divider line either. Is this possible, where/how should I be setting this? 回答1: I've been able to update the divider colour on a PopupMenu using the following

问题 Maybe someone can help me with a little problem in Visual Studio Code, which drives me crazy... ;-/ ... I know how to install and switch different color themes (like "dark-plus" etc.). I found out how to modify things like (in settings.json): editor.tokenColorCustomizations": { "[dark-plus-syntax]": { "comments": "#649664" } But all my googling didn't reveal the most basic modification thinkable: How do I only change the standard editor font color? Any idea how to do this easily? I want to

问题 Java provides some useful character classes like \d and \w . Can I define my own character classes? For example, it would be useful to be able to define shorthands for character classes like [A-Za-z_] . 回答1: Can I define my own character classes? No, you can't. Personally, when I have a (slightly) complicated regex, I break the regex up in smaller sub-regexes and then "glue" them together with a String.format(...) like this: public static boolean isValidIP4(String address) { String block_0

问题 How can I remap alt+backspace to delete words like native *NIX text manipulation? I checked out this thread: Using alt+backspace key in vim command line to delete by words And the examples like: cmap <a-bs> <c-w> and :imap <A-BS> <C-W> don't do anything. And the accepted answer was actually to not even remap it, but to use ctrl+w . Since VIM's alt+backspace doesn't do anything I'd rather remap it to something I'm used to. I'm using terminal based VIM (specifically in iTerm) 回答1: The Alt/Meta
