Re: [Interest] Support for NSDragOperationDelete in Qt Cocoa
Guys, are there any Mac programmers who can help me?) Иван Комиссаров 10.01.2013, в 12:44, Иван Комиссаров abba...@gmail.com написал(а): As i looked into qt code (both qt4 and qt5), it is not possible to enable this flag for a drag and drop. This flag is needed to allow dropping to a mac trash. Is there some reasons why it's not included into Qt::ActionMask and/or MoveAction enums (what i mean - are there some bugs/ limitations in current code, or this can be done easily?). What i suggest - keep current Qt enum, but implicitly convert Qt::MoveAction into flag NSDragOperationMove | NSDragOperationDelete instead of NSDragOperationMove.

Re: [Interest] [gnutls-help] ANNOUNCE: Qt Certificate Addon
On Sun, Dec 16, 2012 at 10:18 PM, Richard Moore r...@kde.org wrote: What is it? === Qt Certificate Addon is a framework for creating X.509 certificates using Qt. Unlike the read-only support for certificates that's included in the SSL module this API allows new certificates, keys and signing requests to be created. Hello Richard, The API looks reasonable. I don't know where this is intended to be used, but it may be useful to have some examples of common usage in the documentation (e.g. how to generate a certificate for a web server). I'd also miss key generation on smart card, but this may not be a popular use-case for a first release. As I see the API it can easily accommodate that in the future. * Key usage * Extended key usage These two proved to be hard to use in the internet. On a survey of certificates in web servers those values seem to be randomly selected based on each admin's understanding of the meaning of the values. The code is capable of creating certificates, keys and signing requests with support for the most common types of certificate extension. The documentation is at a reasonable level, there are examples and a moderate level of unit tests. I've only tested the code on Linux, but apart from the RandomGenerator class it should work fine on all platforms.

Subject: [Interest] animation on font.pixelSize
Hi,
as with Quick2.0 we got the very nice DistanceField-font-rendering.
So in theory animations on Text{ font.pixelSize } should be fairly cheap,
right?
With the following code snipped I got performance problems never the less:
import QtQuick 2.0
Text {
id: text
width: 500
height: 100
text: Test font.pixelSize animation
NumberAnimation {
running: true
loops: Animation.Infinite
duration: 2000
target: text
property: font.pixelSize
from: 10
to: 90
}
}
The strange thing is, on my desktop he has 100% cpu load for the first 2-4
loops.
... I wild guess: It looks like it needs to render the font-glyphs for
each(?) size and after a few cycles it got all of them rendered and
cached...? (it can't render all of them in the first loop as he jumps due
to bad performance)
On embedded (raspberry pi) I get 20% load all the time.
On desktop I got:
- intel xeon 3ghz
- nvidia 8600gts
- Qt5 checkout from this week, branch: stable
- xcb as platform backend (using freetype and fontconfig)
On the raspberry I got:
- BCM 2835 (slow ARM11 cpu, fast VideoCore IV GPU)
- eglfs as platform backend
- no fontconfig - QBasicFontDatabase
(If it helps I can do a fontconfig build)
Is this know? Can anyone verify?
And possible explanation? .. maybe my Qt5 build on desktop is flawed?

Try adding renderType: Text.QtRendering in the Text element. On

not use distance field glyphs but texture glyphs cached based on the
pixel size, maybe even on the scale?).

Hi, I have to admit that I completely missed the existence of the installer framework so far. Before starting further investigations, please let me ask if it is a possible solution for me: I'm maintainer of the Qwt ( http://qwt.sf.net ) library and thought about offering binary packages that are compatible to the offical Qt SDKs. These packages need to be for Windows only as on other platforms binary packages are offered by distributors and/or users are experienced enough for building and installing from source code. Basically all what needs to be done is to copy some files ( libraries, headers, documentatio, prf files - but no application or parts from the Qt installation ) into some install directory and maybe: - adjusting the PATH variable - adjusting QT_PLUGIN_PATH - configuring qmake ( setting QMAKEFEATURES ) Uwe ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

Nice, good to know.
I did a quick test and it seems to be working fine. I'll have to
document my QML now, but that helper is exactly what I needed. Thank
you once again (you can check out the project here:

I noticed, however, that it does not add subcomponents to the

Re: [Interest] animation on font.pixelSize

Hi,
as with Quick2.0 we got the very nice DistanceField-font-rendering.
So in theory animations on Text{ font.pixelSize } should be fairly cheap,
right?
With the following code snipped I got performance problems never the less:
import QtQuick 2.0
Text {
id: text
width: 500
height: 100
text: Test font.pixelSize animation
NumberAnimation {
running: true
loops: Animation.Infinite
duration: 2000
target: text
property: font.pixelSize
from: 10
to: 90
}
}
The strange thing is, on my desktop he has 100% cpu load for the first 2-4
loops.
... I wild guess: It looks like it needs to render the font-glyphs for
each(?) size and after a few cycles it got all of them rendered and
cached...? (it can't render all of them in the first loop as he jumps due
to bad performance)
On embedded (raspberry pi) I get 20% load all the time.
On desktop I got:
- intel xeon 3ghz
- nvidia 8600gts
- Qt5 checkout from this week, branch: stable
- xcb as platform backend (using freetype and fontconfig)
On the raspberry I got:
- BCM 2835 (slow ARM11 cpu, fast VideoCore IV GPU)
- eglfs as platform backend
- no fontconfig - QBasicFontDatabase
(If it helps I can do a fontconfig build)
Is this know? Can anyone verify?
And possible explanation? .. maybe my Qt5 build on desktop is flawed?
Try adding renderType: Text.QtRendering in the Text element. On
desktop it might be that Text.NativeRendering is the default (which does
not use distance field glyphs but texture glyphs cached based on the
pixel size, maybe even on the scale?).
No the default was already renderType: Text.QtRendering
Changing the property does work, as the font is rendered differently with
renderType: Text.NativeRendering
(Especially during the animation one can see how the font is changing with
renderType: Text.NativeRendering, e.g. line-width/boldness is jumping)
The performance behavior seams to be the same.
First 2-4 cycles it's 100% cpu then is drops to 5%
Again from the other side of this thread:
I'm not searching for a quick work-around (e.g. scale), I rather want to
understand why this is happening, why it's different on my rpi and if this is
a bug or a wanted/accepted behavior.
Greets
Thomas
p.s.: (a bit off-topic)
@ cached based even on scale
Scale with renderType: Text.NativeRendering is similar as with Qt4/Quick1:
He renders with the specified font size and scales it during gl-painting
- font.pixelSize: 1; scale: 30 looks extremely unreadable.
Where renderType: Text.QtRendering produces the same output with
font.pixelSize: 1; scale: 30; and font.pixelSize: 30; scale: 1;
(not counting the 'Text' elements geometry properties)

No the default was already renderType: Text.QtRendering
Changing the property does work, as the font is rendered differently with
renderType: Text.NativeRendering
(Especially during the animation one can see how the font is changing with
renderType: Text.NativeRendering, e.g. line-width/boldness is jumping)
The performance behavior seams to be the same.

I don't understand it, the distance field text should not be
re-generated based on pixelSize. Maybe there's something else going on,
since it's on desktop you could run it through callgrind perhaps :)
Greets
Thomas
p.s.: (a bit off-topic)
@ cached based even on scale
Scale with renderType: Text.NativeRendering is similar as with Qt4/Quick1:
He renders with the specified font size and scales it during gl-painting
- font.pixelSize: 1; scale: 30 looks extremely unreadable.
Where renderType: Text.QtRendering produces the same output with
font.pixelSize: 1; scale: 30; and font.pixelSize: 30; scale: 1;
(not counting the 'Text' elements geometry properties)
Good to know :)
