So when trying to add a HoverTool to a plot, the MultiLine Hover works.
But the problem I am having is, that I have another highlighting Single Line, that I do not want the Hover to act on.
So I wanted to input just the multiline to the renderers keyword
p.add_tools(HoverTool(tooltips = [('Name: ', '#Name'),
('Value', '#Value')],
renderers = [multiline]
)
and I am getting the following error:
ValueError: expected an element of either Auto or List(Instance(Renderer)), got [MultiLine(id='4982e76f-7dda-4d78-b729-240c9a29bdef', ...)]
What am I missing?
Glyphs (such as MultiLine) are more like a description of what to draw. There is a seperate GlyphRenderer that takes glyphs and uses them to draw (it can actually have several versions of a glyph to use in different cases, e.g. for selecting and highlighting and decimating). The renderers arg of the hover tool expects the GlyphRenderer, not the glyph.
If you are using bokeh.plotting, then the glyph renderer is returned by the method on the figure:
r = plot.multi_line(...) # r is what to configure on the hover tool
If you are using the low level bokeh.models API then you must already be configuring a GlyphRenderer manually for your MultiLine. Pass that to the hover tool instead.

I like that in Atom text editor, you can hide code blocks to get a better overview. This is called Folding and is described here. There it says:
Finally, you can fold arbitrary sections of your code or text by making a selection and then typing Alt+Ctrl+F or choosing "Fold Selection" in the Command Palette.
I would like to make use of this, but it doesn't work for me. (I select a section of my code, then press the combination Alt+Ctrl+F, but nothing happens.) My operating system is Linux Mint 20.2 and the Atom version is 1.58.0.
I am looking for a fix or for a different method to fold selected text.
My use-case right now would be to fold Python docstrings. So if someone knows how to accomplish only that in Atom, you would also help me.
Although I did not find out why the hotkey doesn't work, I found a solution that fits my needs. The Atom package custom-folds adds the functionality to define regions that may be folded.
After installing custom-folds, I added the lines #<editor-folds and #</editor-fold> at the beginning and end of the docstring, respectively:
def average(a, b):
#<editor-fold
"""
Return the mean value of inputs a and b
"""
#</editor-fold>
return (a+b)/2
The commands #<editor-fold and #</editor-fold> are recognized and highlighted; also, a dropdown arrow appears where the code region can be folded or unfolded.
(First Question so apologies)
Bokeh 1.3.4
Situation:
I am trying top map a Bokeh MultiLine using a CDSView and all the existing examples seem to use the "figure" object which has a helper (multi_line) which accepts a view as an argument. I am doing this on top of a GMAPPlot which does not support multi_line (only MultiLine) (see below). The commented out line throws an error saying GMAPPlot does not support multi_line.
plot = GMapPlot(
x_range=Range1d(), y_range=Range1d(), map_options=map_options, sizing_mode='scale_height'
)
.
.
.
sel_sa1s = []
v_bf = [True if sa1_val in sel_sa1s else False for sa1_val in v_source.data['SA1']]
v_view = CDSView(source=v_source, filters=[BooleanFilter(v_bf)])
v_ml = MultiLine(xs="xs",ys="ys",line_color="black", line_width="w")
#v_rend = plot.multi_line(xs="xs",ys="ys",line_color="black", line_width="w", source=v_source, view=v_view)
v_rend = plot.add_glyph(v_source, v_ml, name='votes')
The snippet shown above works and maps the entire network (very crowded) because there is no filter. What I want to have happen is for the filter to be initialised to hide everything then when the user clicks on an area (SA1) it will display the network related to that SA1.
Actually I can do that but only one area at a time and it would be much more efficient to be able to load the whole map and use a filtered view to control which sub-networks are displayed.
It seems that GMAPPlot only likes the pattern:
create glyph
add glyph
So, my question is - how does one use a CDSView in this environment (how does one add it to the renderer?)

It seems that GMAPPlot only likes the pattern:
create glyph

That has not been true for some time. There is a higher level bokeh.plotting.gmap function that creates and configures GMapPlot instances with deafult axes, etc, and also has all the same methods and conveniences as figure (e.g. multi_line). It will be much less work to go this route than assembling everything by hand from low-level objects.
I'm a new Atom user and I want to override the Atom command palette (shift-ctrl-p) scrolling key bindings to something more vi friendly like
ctrl-n and ctrl-p instead of the annoying arrow keys (which force me to take my hands off the home row).
Just to be clear, I don't want to change the key binding that brings up the command palette, but the key bindings you use to scroll through the list once it's up:
I can only find a binding to override the command palette toggle:
As you can see in the following config file, I was able to override the autocomplete scrolling, and I hope to do the same with the command palette. I've tried 'command-palette:up' ,'command-palette:down' and 'command-palette:move-up' etc. to no avail.
Here's is my keymap.cson.
# Atom Flight Manual:
# https://atom.io/docs/latest/using-atom-basic-customization#cson
#vt add
'body atom-text-editor.autocomplete-active':
'ctrl-p': 'autocomplete-plus:move-up'
'ctrl-n': 'autocomplete-plus:move-down'
'alt-p': 'autocomplete-plus:page-up'
'alt-n': 'autocomplete-plus:page-down'
'home': 'autocomplete-plus:move-to-top'

# add cmd palette key bindings --> These do not work.
'body .native-key-bindings':
'ctrl-p': 'command-palette:up'
'ctrl-n': 'command-palette:down'
#vt end
I've been really impressed with the key binding support in Atom thus far. I'd be really surprised if it couldn't handle this but, alas, I think this might be the case.
Does anyone know of a way to do this?
Atom 1.7.2, linux
I was able to get single line scroll to work, but not page scroll to work with the following in my keymap.cson:
'atom-workspace':
# these work
'ctrl-p' : 'core:move-up'
'ctrl-n' : 'core:move-down'
# these don't work
'alt-p' : 'core:page-up'
'alt-n' : 'core:page-down'
It would be nice to have page scroll as well, but I should be able to narrow down the list down by typing in text, so I don't foresee needing page-up, page-down all that often.
Now I'm happy.
To target keybindings for just the command palette, you can find an appropriate selector by looking in the command-palette repo keymaps: https://github.com/atom/command-palette/blob/v0.43.5/keymaps/command-palette.cson
This suggests the use of the .command-palette selector, which seems more appropriate then atom-workspace.
'.command-palette':
'ctrl-n': 'core:move-down'
'ctrl-p': 'core:move-up'
I was not able to find a mapping to scroll a page at a time within the command palette, though I'm sure someone else can figure it out. The keyboard page up/down keys have no effect so mapping to core:page-down etc. is not going to work.
I'm trying to display different language strings in my qt app by inserting each language into a QMap<QString, QString> so it can be re-used in several places and put into different combo Boxes across the application. I do this by
creating the QMap like so in the CTOR:
m_langMap.insert(QString::fromWCharArray(L"English"), "english");
m_langMap.insert(QString::fromWCharArray(L"Dansk"), "dansk");
m_langMap.insert(QString::fromWCharArray(L"Nederlands"), "dutch");
m_langMap.insert(QString::fromWCharArray(L"Čeština"), "czeck");
m_langMap.insert(QString::fromWCharArray(L"Slovenský"), "slovak");
m_langMap.insert(QString::fromWCharArray(L"Magyar"), "hungarian");
m_langMap.insert(QString::fromWCharArray(L"Român"), "romanian");
m_langMap.insert(QString::fromWCharArray(L"Latviešu"), "latvian");
m_langMap.insert(QString::fromWCharArray(L"Lietuvių"), "lithuanian");
m_langMap.insert(QString::fromWCharArray(L"Polski"), "polish");
m_langMap.insert(QString::fromWCharArray(L"Português"), "portuguese");
m_langMap.insert(QString::fromWCharArray(L"Español"), "spanish");
m_langMap.insert(QString::fromWCharArray(L"Français"), "french");
m_langMap.insert(QString::fromWCharArray(L"Italiano"), "italian");
m_langMap.insert(QString::fromWCharArray(L"Svenska"), "swedish");
m_langMap.insert(QString::fromWCharArray(L"Русский"), "russian");
m_langMap.insert(QString::fromWCharArray(L"Українська"), "ukranian");
m_langMap.insert(QString::fromWCharArray(L"Русский"), "russian");
m_langMap.insert(QString::fromWCharArray(L"中文"), "chinese");
m_langMap.insert(QString::fromWCharArray(L"日本語"), "japanese");
I then insert them into the combo box:
QMap<QString, QString>::const_iterator it = m_langMap.begin();
while (it != m_langMap.end())
{
ui->comboBox->addItem(it.key());
++it;
}
When the app runs, I see the following:
However, if I create a separate .ui file and insert the map the same way, I see the following (even if I include this separate Dialog class into the same application), so clearly there is no font issue as far as the App not knowing how to render the different character sets....yet I cant figure out why the first one won't render the character sets?
Can someone tell me why the first doesn't work but the second does? I checked the Designer and its Locale is set to 'C, Default' in both ui files I've shown below. I can't seem to figure out what else is causing the difference for the first not to work, and the second does work within the same application.
Thanks for any help!
The other test Dialog:
Your code is correct, but the problem is that your source file cannot contain Unicode characters - apparently it is using different coding.
Save file as UTF-8 and everything should work!
In the first screenshot the font used by the combobox is much larger than in the second screenshot. My guess is that you have changed the font either in the GUI designer or in the code and the second (working) screenshot is using the default font. It might be that when you have changed the font size, you have also changed the font to something that doesn't contain all the required Unicode characters. Try changing the font used by the combobox to something else.
I have a flex 4.5 application. I want to add new line in an mx:TextArea when certain event occurs. I have been searching for the proper way to add a OS independent line ending. I found out that the File class has lineEnding property. However the documentation states that this class is not exposed when running inside a browser (which is my case).
I have searched, but I couldn't find any other class, which can provide this information. Actually I am not sure if the TextArea line ending is OS dependent or not.
So actually I have two questions: Are TextArea line endings OS dependent or not? And if so, how can I get the proper line ending in flex?
You can use String.fromCharCode(13). This will return a line ending.
This is the equivalent of PHP's chr() method.
Example:
var address_str:String = "dog" + String.fromCharCode(64) + "house.net";
trace(address_str); // output: dog#house.net
From my experience, "\r" works in both Windows and Mac.
Quite simply, you just need to add the newline character to the text of the textArea.
myTextArea.text+="\n"; //This should work, if not try the other two
myTextArea.text+="\r";
myTextArea.text+="\r\n";
