Hi, I want to set rounded corners on a QDialog. Since it is a top-level window, border-radius doesn't work, so I've to do this : QRegion EnterPinDialog::roundedRect(const QRect& rect, int r) { QRegion region; // middle and borders region += rect.adjusted(r, 0, -r, 0); region += rect.adjusted(0, r, 0, -r); // top l...

I am trying to make an icon for my Qt 4.6.3 application, which is currently running on Symbian S60 5th edition. The application runs fine, except for its icon, which I have been unable to set by any means. I have read and tried a number of articles, including [1], [2], [3], [4] and [5], but in vain. What could I be doing wrong, or what s...

The main view of my application contains a one-level (no children) QTreeView that displays on average 30,000 items. Due to the way the items are created, they are inserted into the model unsorted. This means that on application startup I have to sort the items in the view alphabetically, which takes nearly 1 second, leaving an unresponsi...
I'm currently producing PDFs using python and PyQT. I'd like to change the "Producer" value of the PDF's document information, currently it is set to "Qt 4.6.2 (C) 2010 Nokia Corporation and/or its subsidiary(-ies)". I've looked through the QPrinter reference, and nothing obvious stuck out that I could set. How do I change the docum...

Hi. I have an application where a QGraphicsPolygonItem (objectA) has the following characteristics: ScenePos: X=250 Y=125 Transform(): |----|---|---| | 2 | 0 | 0 | | 0 | 1 | 0 | | 50 | 0 | 1 | |----|---|---| Now, I am creating and new QGraphicsPolygonItem (objectB) and setting its scenepos and Transform the same as object A: obj...
I really like using the _countof() macro in VS and I'm wondering if there is an OS-generic implementation of this in Qt. For those unaware, _countof() gives you the number of elements in the array. so, wchar_t buf[256]; _countof(buf) => 256 (characters) sizeof(buf) => 512 (bytes) It's very nice for use with, say, unicode strings, wh...
Hi All, I'm a newbee to Qt and qmake and I like to know if it's possible to instruct qmake to build a "Bundle Library" (mh_bundle) under Mac OS X using the TEMPLATE and CONFIG variables? I already managed to make a "Dynamic Library" (mh_dylib) and a "Framework" (mh_dylib). If there is no direct solution, how is the best way to achieve t...

I thought I had this all figured out, but now that I'm writing a webserver, something is not quite working right. The app listens on a port for incoming requests, and when it receives one, it reads everything up to the sequence "\r\n\r\n". (Because that signifies the end of the headers - yes, I am ignoring possible POST data.) Now, aft...
Hi! I'm (once again) struggling with the creation of precompiled headers in conjunction with gcc and Qt on the Apple platform. When now creating my precompiled header I use a code section (based on good old "PCHSupport_26.cmake") to extract the compile flags as follows: STRING(TOUPPER "CMAKE_CXX_FLAGS_${CMAKE_BUILD_TYPE}" _flags_var_n...
I want to detect when the mouse cursor moves in over a QGraphicsItem while a mouse button is pressed, i.e. the button is pressed before the mouse enters the item. My first idea was to use hoverEnterEvent, but it doesn't seem to trigger when the left mouse button is pressed. My other idea was to use dragEnterEvent, but it doesn't seem to ...
