Anthony Geoghegan My output should look like define temp 10 i. I edited the question to better see what is what. If I understood your intent wrong, please edit further!
If your output is without them, there's something else going on! As it is know, your question does not really have enough details to answer accurately. Thanks for your response. It solved my query.. Simplified returned the hidden white spaces. Note: On systems where the system API doesn't report the location of the file in the trash, fileName will be set to the null string once the file has been moved. On systems that don't have a trash can, this function always returns false.
Returns true if successful, and sets pathInTrash if provided to the path at which the file can be found within the trash; otherwise returns false. Note: On systems where the system API doesn't report the path of the file in the trash, pathInTrash will be set to the null string once the file has been moved. Opens the file using OpenMode mode , returning true if successful; otherwise false.
Note: In WriteOnly or ReadWrite mode, if the relevant file does not already exist, this function will try to create a new file before opening it. Opens the existing file handle fh in the given mode.
When a QFile is opened using this function, behaviour of close is controlled by the AutoCloseHandle flag. If AutoCloseHandle is specified, and this function succeeds, then calling close closes the adopted handle. Otherwise, close does not actually close the file, but only flushes it. Sequential devices, such as stdin and stdout, are unaffected by this limitation.
You need to enable support for console applications in order to use the stdin, stdout and stderr streams at the console.
To do this, add the following declaration to your application's project file:. Opens the existing file descriptor fd in the given mode. Warning: If fd is not a regular file, e. In those cases, size returns 0. Warning: Since this function opens the file without specifying the file name, you cannot use this QFile with a QFileInfo. Removes the file specified by fileName. Renames the file currently specified by fileName to newName. If a file with the name newName already exists, rename returns false i.
If the rename operation fails, Qt will attempt to copy this file's contents to newName , and then remove this file, keeping only newName. If that copy operation fails or this file can't be removed, the destination file newName is removed to restore the old state. Renames the file oldName to newName.
Call close when you are done with the device. QIODevice distinguishes between two types of devices: random-access devices and sequential devices. Random-access devices support seeking to arbitrary positions using seek. The Overflow Blog The Bash is over, but the season lives a little longer.
The file name is usually passed in the constructor, but it can be set at any time using setFileName. Toggle navigation Cordylink.
