Detect touch press vs long press vs movement?

This code can distinguish between click and movement (drag, scroll). In onTouchEvent set a flag isOnClick, and initial X, Y coordinates on ACTION_DOWN. Clear the flag on ACTION_MOVE (minding that unintentional movement is often detected which can be solved with a THRESHOLD const). private float mDownX; private float mDownY; private final float SCROLL_THRESHOLD = 10; … Read more

Move / Copy File Operations in Java

Here’s how to do this with java.nio operations: public static void copyFile(File sourceFile, File destFile) throws IOException { if(!destFile.exists()) { destFile.createNewFile(); } FileChannel source = null; FileChannel destination = null; try { source = new FileInputStream(sourceFile).getChannel(); destination = new FileOutputStream(destFile).getChannel(); // previous code: destination.transferFrom(source, 0, source.size()); // to avoid infinite loops, should be: long count … Read more

Python – Move and overwrite files and folders

This will go through the source directory, create any directories that do not already exist in destination directory, and move files from source to the destination directory: import os import shutil root_src_dir=”Src Directory\\” root_dst_dir=”Dst Directory\\” for src_dir, dirs, files in os.walk(root_src_dir): dst_dir = src_dir.replace(root_src_dir, root_dst_dir, 1) if not os.path.exists(dst_dir): os.makedirs(dst_dir) for file_ in files: src_file … Read more

Usage of std::forward vs std::move

You cannot use std::forward without explicitly specifying its template argument. It is intentionally used in a non-deduced context. To understand this, you need to really understand how forwarding references (T&& for a deduced T) work internally, and not wave them away as “it’s magic.” So let’s look at that. template <class T> void foo(T &&t) … Read more

How do I move a file from one location to another in Java?

myFile.renameTo(new File(“/the/new/place/newName.file”)); File#renameTo does that (it can not only rename, but also move between directories, at least on the same file system). Renames the file denoted by this abstract pathname. Many aspects of the behavior of this method are inherently platform-dependent: The rename operation might not be able to move a file from one filesystem … Read more

How do I move a single folder from one Subversion repository to another repository?

If you have access the repository itself (not a working copy), you should be able to dump the current repository, filter it to only include information about the docs folder, and load it into the other repository. Would be something like this: svnadmin dump /svn/old_repos > ./repository.dump svndumpfilter include path/to/docs –drop-empty-revs –renumber-revs –preserve-revprops < ./repository.dump … Read more

Move column by name to front of table in pandas

We can use loc to reorder by passing a list: In [27]: # get a list of columns cols = list(df) # move the column to head of list using index, pop and insert cols.insert(0, cols.pop(cols.index(‘Mid’))) cols Out[27]: [‘Mid’, ‘Net’, ‘Upper’, ‘Lower’, ‘Zsore’] In [28]: # use ix to reorder df = df.loc[:, cols] df … Read more
