[Interest] QDateTime: time part is "00:00:00" in "Locals & Expressions"

2017-07-20 Thread mail
Hi, variables of QDateTime type are apparently not displayed correctly in "Locals & Expressions", the time information is missing. While the date part is shown correctly, the time is always 00:00:00. The same variable prints just right with qDebug(). QtCreator (rather: gdb?) shows: "re

[Interest] QMetaType::type() enum scope

2017-07-20 Thread Jérôme Godbout
Hi, we are trying to recover the QMetaType id from a class enum (Qt 5.5). It seem to work into some .dll but not others. We have a class with registered Qml class that have an enum registered too like the following. It seem to work just fine into the QmlOtherObj but not the QmlGlobalObject::enumS

Also it should be between two arbitrary points, so the sine wave may go from top-right to bottom left, for example. > On Jul 20, 2017, at 1:28 AM, Elvis Stansvik wrote: > > 2017-07-20 10:23 GMT+02:00 Jean-Michaël Celerier > mailto:jeanmichael.celer...@gmail.com>>: >> You can just compute the si

You can just compute the sine directly : for(int i = 0; i < width; i++) { int x = i; int y = height / 2 + amplitude * std::sin(2 * M_PI * freq * i / width + phase); path.lineTo(x, y); } --- Jean-Michaël Celerier http://www.jcelerier.name On Thu, Jul 20, 2017 at 9:

[Interest] sin wave with QPainterPath between two points

2017-07-20 Thread Patrick Stinson
Hello! I want to figure out how to draw a sin wave between two QPointF’s using QPainterPath. Calculating the cubic control points seems like the best way, but I am far from mastering that theory. This is a diagramming app and the goal is to get a squiggly line between two objects. Thanks! smi
