Detailed Description

Dialog for merging documents.

 Usage:

 // Create dialog instance
 MergeDialog * dialog=new MergeDialog();

 // Inits original document (one which is currently opened) with its page
 // count.
 dialog->initOriginal(pageCount);

 // Starts dialog as modal and does something if OK was pressed
 if(dialog->exec()==QDialogAccepted)
 {
      // gets result of merging operation
      MergeDialog<int> * result=dialog->getResult();

      // if result length is 0 - there is nothing to merge
      if(result->getLength()>0)
      {
              // result->getItems() returns an array of pages to be merged
              // with current document
              // result->getPositions() returns an array of positions for
              // those pages
      }

      // result cleanup
      delete result;
 }

 // dialog cleanup
 dialog->destroyOpenFile();
 delete dialog;

void gui::MergeDialog::destroyOpenFile ( )

Clean up for opened file.

Destroys everything what was created during initFileList.

void gui::MergeDialog::downBtn_clicked ( ) [virtual, slot]

Slot called when button "Down" to move page down in the document is clicked

QString gui::MergeDialog::fileName ( )

Return file name of document that contain pages to merge

Returns:: filename of selected document

MergeArray< int > * gui::MergeDialog::getResult ( )

Returns result of merging.

Creates MergeArray instance (Note that caller is responsible for deallocation) and fills it according current state of mergeList as follows:
Collects all ListItems from mergeList with FROMFILE node data type. MergeArray's length is number of these items. Items arrray is then initialized with ORIGINAL item position which is before FROMFILE item (starting from 1 for items which are at the begining).
As a result items array contains page positions (in opened file) which should be merged and positions array contains page positions from original file before which they should be inserted.
TODO - maybe use shared_ptr<CPage> as parameter...

bool gui::MergeDialog::initFileList ( QString & fileName ) [protected]

Fills fileList with ListItems corresponding to pdf document given by name.

Parameters:

fileName

Pdf document name to merge with original one.

Gets page count from given file and creates entries (ListItem instances with NodeData with FROMFILE type) for fileList list box.

Parameters:

fileName

name of PDF file

Returns:: true in case of success, false in case of failure (missing ,broken or unreadable pdf file)

Parameters:
