问题 I have a JTree with editable nodes. How can I programmatically trigger the tree cell edit event, i.e. bring up the node-renaming textbox in place of a highlighted node, as if the user manually highlighted it and pressed F2? Basically I want to add a "Rename" menu item or toolbar button, to clue users in on that particular function of the tree, and I want it to function identically to an F2 keypress when the user highlights a node. 回答1: 1) some node is selected (by Mouse / KeyBoard event) and

问题 Does anyone know what is the syntax for renaming a mysql stored procedure/function? Or is this even supported in MySQL? I've been googling this for several minutes... 回答1: try this UPDATE `mysql`.`proc` SET name = '<new_proc_name>', specific_name = '<new_proc_name>' WHERE db = '<database>' AND name = '<old_proc_name>'; Also note: If have granted privileges to users for this procedure you will need to update the procedure name in procs_priv as well. UPDATE `mysql`.`procs_priv` SET Routine_name

问题 I want to rename a large number of files in increasing order of numbers, starting from anywhere. But when I rename multiple files, it leaves me with parentheses. eg i rename files to abc_.jpeg it results in abc_(1).jpeg, abc_(2).jpeg and so on. I tried using command prompt to rename ren abc_(*).jpeg abc_*.jpeg doesn't work. probably because of brackets ren abc_"("*")".jpeg abc_*.jpeg renames the files, but results in the same file name as before. I just want to remove the parentheses somehow.

问题 I've just started experimenting with adding an iOS 8 Today Widget to my app, it's going ok so far but I followed the original template and got my widget created with TodayWidget as its name. In the context of my app's files in Xcode that target/product name is fine. But sadly this is the name that also displays within notification centre, above my widget. I've tried tracing through various names in my project that match what's being displayed but so far I've yet to find one that lets me

问题 I cant figure out how to update/rename a file uploaded/managed with Carrierwave-mongoid in rails 3.2.6. I want to rename the file in the db as well as on the filesystem. Something like this maybe... def rename( id , new_name ) f = UploadedFile.find(id) if f.update_attributes({ f.file.original_filename: new_name }) # this is WRONG, what is right??? new_path = File.join( File.dirname( f.file.current_path ) , new_name )) FileUtils.mv( f.file.current_path , new_path ) end return f end Let me add

问题 After renaming a table in Postgres I'm experiencing a strange behaviour: if I reference the table without the quotes it doesn't work. For example: the original name was «devices», after I've altered it to «Devices» the following SELECT breaks: SELECT * from Devices but this one SELECT * from "Devices" works as expected. Any idea? 回答1: Per the manual, identifiers are lower-cased unless quoted. When you renamed it you did a RENAME TO "Devices" , thus making the name mixed-case. You must now

问题 I have an existing file in my HDD and I want rename this file. 回答1: Like this: new File(path).renameTo(new File(newPath)); 回答2: You may look at commons-io FileUtils.moveFile. That method tries File.renameTo, and if that fails, tries to copy&delete the file (e.g. when moving from one drive to another). If you use File.renameTo directly (which should suffice if you only want to rename a file in the same directory), make sure you evaluate the returned boolean value! 来源： https://stackoverflow.com

问题 Is there an easy way to rename a controller and model in my app and all the instances in the corresponding code? I'm using textmate, would this be as simple as using the replace function and replacing the word Post with Report? 回答1: If you are using textmate, use 'command-shift-f" to look for a string throughout your entire project. 回答2: You need to change the name of the Controller and the associated Model , Views , Helpers , Tests & Routes directories, file names, class names & the names in
