2013-08-05Print: improve table printing by using QTableViewGravatar Lubomir I. Ivanov
The current QTextDocument implementation is slow due to HTML parsing. By using QTableView with QAbstractTableModel we boost the performance of the table print drastically. This patch completely replaces the old solution. There is a hidden QTableView widget which is populated with all data and rendered using a QPainter attached to the printer device. A couple of new classes are added in models.h/cpp that handle the table print model and these are then used in printlayout.h/cpp. Signed-off-by: Lubomir I.

2013-07-18Print: add method to convert profile to grayscaleGravatar Lubomir I. Ivanov
(experimental) Add the method PrintLayout::convertPixmapToGrayscale() to convert a rendered profile pixmap to grayscale. It will probably be faster to have ProfileGraphicsView render in grayscale under certain conditions (and use a specific color table) instead - e.g.: ProfileGraphicsView::setPrintMode(bool printMode, bool useGrayScale); Signed-off-by: Lubomir I.

2013-07-11Print: mark some functions in PrintLayout as 'const'Gravatar Lubomir I. Ivanov
It might be a good practice to declare certain class 'helper' functions as constant members. But I don't think there are performance benefits to that other than the readability ones. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2013-07-11Print: show column titles for table printGravatar Lubomir I. Ivanov
Patch does: - set individual column width and name (held in tableColumnNames, tableColumnWidths) - reduce font size in the table - more small tweaks in the style sheet TODO: finish printing all dive data Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2013-07-11Print: move some header includes to cpp filesGravatar Lubomir I. Ivanov
We don't really need includes of display.h and dive.h in printoptions.h and printlayout.h or forward declartions of 'struct dive' and 'struct options' in there. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2013-07-10Print: use the actual dive tableGravatar Lubomir I. Ivanov
Currently only for the table print, but now we use the actual dive table to iterate trough all dives (find only selected if needed) and print their 'number' element in table rows. Also improves the new-page detection algorithm slightly. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2013-07-10Print: initial implementation of the table printGravatar Lubomir I. Ivanov
PrintLayout for now only handles the table print, while the data output itself is work in progress. For now there is a simple HTML/CSS table logic based on QTextDocument. There is an iterative algorithm which listens for a page increase and adds a heading on top of the new page. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2013-07-10Print: add a setup() method to PrintLayoutGravatar Lubomir I. Ivanov
The setup() method will be called each time to obtain the current printer settings. Also it calculates required scalling based on screen agains printer DPI. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
2013-07-10Print: add a class for print layoutingGravatar Lubomir I. Ivanov
PrintLayout is a class that will handle the layouting part of dive profiles, text, tables depending on the settings of a QPrinter and the PrinterDialog and PrintOptions instances. Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>
