It is possible to use local images, I have tried the following ways but none have worked :(
background_image = "url(https://i.ibb.co/DknqgWf/test.png)" // This one works
background_image = "url(~/termux/gotty/wallpapers/wallpaper-1.png)"
background_image = "url(./termux/gotty/wallpapers/wallpaper-1.png)"
background_image = "url(/data/data/com.termux/files/home/termux/gotty/wallpapers/wallpaper-1.png)"
The doc says it's a css property, so it should work but it doesn't :(
version : 1.0.1
SO: Android
how about
background_image = "url(file:///data/data/com.termux/files/home/termux/gotty/wallpapers/wallpaper-1.png)"
maybe only two // wherer I have three /// - but posix should always squash too many / to one.

Below a screenshot of my application. I want to get rid of the white spaces after the last tables lines marked by red rectangles :
The horizontal size policy is expanding and the vertical one is minimum and for other tables it is both set to expanding.
I'm using this method I found in another SO question but as you can see the result is not flawless.
void verticalResizeTableViewToContents(QTableView* tableView)
{
tableView->resizeRowsToContents();
// does it work ?
tableView->setSizeAdjustPolicy(QAbstractScrollArea::AdjustToContents);
int rowTotalHeight = 0;
// Rows height
int count = tableView->verticalHeader()->count();
for (int i = 0; i < count; ++i) {
// 2018-03 edit: only account for row if it is visible
if (!tableView->verticalHeader()->isSectionHidden(i)) {
rowTotalHeight += tableView->verticalHeader()->sectionSize(i);
}
}
// Check for scrollbar visibility
if (!tableView->horizontalScrollBar()->isHidden())
{
rowTotalHeight += tableView->horizontalScrollBar()->height();
}
// Check for header visibility
if (!tableView->horizontalHeader()->isHidden())
{
rowTotalHeight += tableView->horizontalHeader()->height();
}
tableView->setMaximumHeight(rowTotalHeight);
}
Somewhere, I'm using this code to setup one of the tables :
m_Internals->Ui.Measures->setModel(mm->getPh66MeasuresModel());
m_Internals->Ui.Measures->horizontalHeader()->setSectionsMovable(true);
m_Internals->Ui.Measures->horizontalHeader()->setHighlightSections(false);
m_Internals->Ui.Measures->horizontalHeader()->setSectionResizeMode(QHeaderView::Interactive);
m_Internals->Ui.Measures->horizontalHeader()->setStretchLastSection(true);
m_Internals->Ui.Measures->verticalHeader()->hide();
m_Internals->Ui.Measures->setSelectionBehavior(QAbstractItemView::SelectRows);
verticalResizeTableViewToContents(m_Internals->Ui.Measures);
I'm using Qt ModelView pattern to populate/update the tables.
Update : I made a small example to reproduce this issue with QTableView : https://github.com/embeddedmz/QTableViewAdjustPolicyNotWorkingProperly
Using the latest Qt version (from Qt official installer), there's no issue. However, using the Qt library provided by vcpkg (outdated for sure) the issue is there.
With Qt provided by vcpkg :
With the latest Qt provided by the Qt Company (update not the latest, it's 5.12.11) :
If you have something fully buildable on Ubuntu 20.04 LTS, post a link to the complete project (strip it down to just this part) and I will take an actual stab at it.
My gut, having worked with Qt for years, is telling me you are being burned by Margins.
https://doc.qt.io/qt-5/qwidget.html#contentsMargins
You probably need to set a bottom margin of Zero.
https://doc.qt.io/qt-5/qmargins.html#setBottom
If you retrieve the margins for those widgets you will probably find they are non-zero.
you can also fix your problem with one trick, this problem happens for you because your data is lower than the table size. I clone your project and change sizepolicy
Under Qt 5.12.11, the bug does not exist. So I took a look at the QAbstractScrollArea::sizeHint code of this version and compared it with the implementation used in recent versions of Qt and found that setting verticalScrollBarPolicy to "ScrollBarAlwaysOff" the "AdjustToContents" adjustment policy works. The default value was "ScrollBarAsNeeded", in fact we can see that this value is not handled but since in Qt 5.12.11 we only compare the vertical|horizontal]scrollBarPolicy to Qt::ScrollBarAlwaysOn it prevents this bug from appearing.
So I’m trying to make a development environment that’s easily reproducible (staying away from home-manager currently to understand Nix better). After enough searching around I figured out how to make a few custom derivations, use buildEnv for package sets, and use ~/.config/nixpkgs/config.nix to do overrides. I’m working now to setup zsh and oh-my-zsh which have a ton of configuration options, but the only documentation I can find seems to suggest adding them to configuration.nix, which is a NixOS option I can’t use.
Currently my config.nix code looks something like this:
let
pkgs = import <nixpkgs> {};
in {
allowUnfree = true;
programs = {
zsh = {
enable = true;
promptInit = "source ${pkgs.zsh-powerlevel9k}/share/zsh-powerlevel9k/powerlevel9k.zsh-theme";
ohMyZsh = {
enable = true;
plugins = ["autojump"];
theme = "powerlevel9k/powerlevel9k";
};
};
};
packageOverrides = pkgs: with pkgs; rec {
all = buildEnv {
name = "all";
paths = with pkgs; [
tmuxinator
zsh
oh-my-zsh
autojump
...
];
};
};
}
My understanding so far is that within ~/.config/nixpkgs/config.nix, there should be a single config set which contains things like the overrides function and corresponds to documentation examples of config.programs.zsh.enable, etc. However, nothing I write in that programs section affects or causes a different ouput of any of my programs.
What am I missing? How can I affect the configuration options listed here (https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/programs/zsh/zsh.nix)?
You seem to be trying to use home-manager's config without using home-manager itself. As you can see in the NixOS module you linked, this actually sets up /etc/zshrc etc, so it's not intended for use in a user-local config and won't do anything there. If you look at the corresponding home-manager module, you'll see that it basically reimplements the whole module for user-local purposes. So you won't get far with this approach without relying on home-manager.
I am trying to create a PostScript file using the Apache xml-graphics library. When I run under Java, it works fine.
But when I build for .NET using IKVM, then on a call to GlyphVector.getoutline(x, y), the code never returns.
This is happening when I:
AttributedString as = new AttributedString(buf.toString());
// call as.addAttribute() setting various TextAttribute for various ranges
FontRenderContext frc = graphics.getFontRenderContext();
LineBreakMeasurer lineMeasurer = new LineBreakMeasurer(as.getIterator(), frc);
TextLayout layout = lineMeasurer.nextLayout(Integer.MAX_VALUE);
layout.draw (graphics, left, line.getBaseline());
Any idea what can be going wrong?
thanks - dave
I've searched the net but cannot find any pretty graphite templates that can be placed in graphtemplates.conf and used in the graph by adding ?template=[name] to the query string.
I found the solarized-light template which looks as follows:
[solarized-light]
background = #fdf6e3
foreground = #657b83
majorLine = #073642
minorLine = #586e75
lineColors = #268bd2,#859900,#dc322f,#d33682,#db4b16,#b58900,#2aa198,#6c71c4
fontName = Sans
fontSize = 10
fontBold = False
fontItalic = False
This one is nice but I want to be able to select more options. Does anyone have or found a good template which I can use?
I couldn't find anything either, so I started one: https://github.com/phillbaker/graphite-templates. Currently has solarized-light (from your post) and solarized-dark. I opened an issue to add monokai as well.
I'm trying to create a VolumeSlider widget that changes the volume of my audio output.
log.debug("Starting audio player (%s)..." % url)
mediaSource = Phonon.MediaSource(url)
mediaSource.setAutoDelete(True)
self.player = Phonon.createPlayer(Phonon.VideoCategory, mediaSource)
self.player.setTickInterval(100)
self.player.tick.connect(self.updatePlayerLength)
self.mediaSlider.setMediaObject(self.player)
audioOutput = Phonon.AudioOutput(Phonon.MusicCategory)
Phonon.createPath(self.player, audioOutput)
self.mediaVolumeSlider.setAudioOutput(audioOutput)
self.player.play()
However even though I can move the volume slider, the actual volume doesn't change. What did I miss?
I have never used Phonon.createPlayer, because the API seems totally baffling. Apparently, it is supposed to be a "convenience" function that creates a path between an media object and an audio output. But it only gives a reference to the media object. There appears to be no access to the audio output object, which would seem to make it completely useless (but I may well be missing something).
Anyway, I think it is much more convenient to create the paths explicitly, so that it is clear how all the parts are connected together.
The following code works for me on Linux and WinXP:
self.media = Phonon.MediaObject(self)
self.video = Phonon.VideoWidget(self)
self.audio = Phonon.AudioOutput(Phonon.VideoCategory, self)
Phonon.createPath(self.media, self.audio)
Phonon.createPath(self.media, self.video)
self.slider = Phonon.VolumeSlider(self)
self.slider.setAudioOutput(self.audio)
