qt - How do I resize QTableView so that the area is not scrolled anymore -

-

I want to keep the size of QTableView equal to that table (and default) so that it is not a scrollbar

What you can do is calculate your table view column width according to their data (or you can change the size of each column Can call up to column-to-continents for size on their content). Then, if the width of the tableview is equal to equal or greater then change the total width of the column + vertical headers if shown. If you have been shown the horizontal header then you will need to track the model changes and adjust your table view width, you can resize the columns and adjust them again, there is some sample code for this below: / P>

Initialization: 

  // Add 3 columns in the table view control table-> Insert column (0, QModelIndex ()); Table modal-> Insert column (1, qmdale index ()); Table modal-> Insert column (2, qmdale index ()); ... // Close horizontal scrollbar; Although it is not really needed here, Iui- gt; TableView-> Set Horizontal ScrollBarPolicy (Qt :: ScrollBarAlwaysOff); // adjusted size; See the code below the adjustment (); // Connect horizontal header resize event (header is not shown if it is not needed) Connect (ui- & gt; Table view-> horizontal header), signal (section rhesis (int, int, int)), This, SLOT (updateSectionWidth integer, integer, integer))); // Connect to the data exchange event of the model (ui- & gt; Table view- & gt; Model ()), signal (data changelief (qmdell index, qmdel index)), this slot (data changed (qmdel index, qmdel Indexes));

Adjust the table view size: 

  zero main window :: adjustable size () {ui-> Table view- & gt; Change shape CollumnToContents (0); UI- & gt; TableView-> ResizeColumnToContents (1); UI- & gt; TableView-> ResizeColumnToContents (2); QRect rect = ui- & gt; Table view- & gt; Geometry (); Rect.setWidth (2 + ui- & gt; Table View- & gt; Vertical Header () - & gt; Width () + ui- & gt; Table View- & gt; Column Width (0) + ui- & gt; ; Table view- & gt; column width (1) + UI-> TableView-> columnWidth (2)); UI- & gt; TableView-> SetGeometry (Rect); }

Process model change 

  Zero main window :: Data changelog (Const. Qmdell index and top left, consume cumdel indices and oakright) {adjusting Deserving (); }

Change the shape of the horizontal header 

  zero MainWindow :: updateSectionWidth (int logical indices, int, int newSize) {adjustTableSize (); }

Hope this helps,

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som
