What are the new frames?
Generally speaking:
Visually
CSS. There are numerous techniques for laying content out (depending on the precise effect you want, Holy Grail is a common desire).
The overflow
properties handle scrolling sub-sections of pages, although designers who think that having a menu using up screen space all the time is a good idea are usually wrong.
Avoiding duplication of metacontent
(i.e. putting things like basic structure, navigation menus, etc on every page without copy/pasting them)
A template system (or an include system) that either runs server side (most common) or at build time (which can support HTTP servers which only allow static files).
The language this is implemented in is irrelevant, PHP is as common as muck, Java is an option, I tend towards Perl (and more specifically: Template Toolkit), there are many others. JavaScript is becoming increasingly popular for this type of job, with tools such as assemble becoming available. You can go all the way with a static site generator.
Use a search engine to find popular template languages or include systems for your programming language of choice.
Loading new content without leaving the page
JavaScript, usually with the XMLHttpRequest object (the technique being known as Ajax), and (if you are doing serious content changes) used in combination with the History API (so bookmarking and linking still works). Github are a good example of this. There are various frameworks such as React and Angular which try to make things easier. Note limited browser support and all the other things that can cause JS to file makes using good design principles essential. One approach to making these things robust is to write Isomorphic JS.
Access a new frames methods
From your comments I think you declare NewCustomer
like this:
JFrame NewCustomer;
If so try declaring:
NewCustomerView NewCustomer;
or
public void ShowNewCustomerView() {
if (NewCustomer == null) NewCustomer = new NewCustomerView(this);
((NewCustomerView)NewCustomer).ClearFields();
NewCustomer.setVisible(true);
}
Append 2 data frames into 1 new data frame
You may need to add the parameter sort=False
like this:
df_3 = pd.concat([df1, df2], ignore_index=True,sort=False)
Output:
Ref Amount Receiver Payer Month
0 1 2000 X Chris Jan
1 2 2222 Y Jinnn Jan
2 3 3002 Z Chhhh Jan
3 4 10000 ZZ BBBB Jan
4 5 25233 ZZZ CCCCC Jan
5 1 3000 111 AAA Feb
6 2 4000 222 BBB Feb
7 3 5000 333 CCC Feb
8 4 6000 444 DDD Feb
9 5 6000 555 EEE Feb
Why flutter creates new frames when nothing changes
Because of processor, app needs processor power every second to be run. So new frames constantly build.
For example:- if you have a phone which has low powered processor and graphics render, you will see frame drops.
Combining a list of data frames into a new data frame in R
Note that in your list of dataframes (df_list
) all the columns have different names (Area1
, Area2
, Area3
) whereas in your output dataframe they all have been combined into one single column. So for that you need to change the different column names to the same one and bind the dataframes together.
library(dplyr)
library(purrr)
result <- map_df(df_list, ~.x %>%
rename_with(~"Area", contains('Area')), .id = 'FileName')
result
# FileName Area
#1 a1_areaX 100
#2 a2_areaX 200
#3 a3_areaX 300
request rendering of new frames in kepler.gl
actually, I managed to get the animation working by porting the code in the question to the kepler.gl app.js in the following way:
first, add the following method into the App class definition:
class App extends Component {
_animate() {
this.setState({});
this._animation = window.requestAnimationFrame(this._animate);
}
then, add in componentDidMount() {
this._animate();
add in componentWillMount() {
//(this line is called in the App's constructor in the deck.gl examples.)
this._animate = this._animate.bind(this);
and finally in componentWillUnmount() {
window.cancelAnimationFrame(this._animation);
what (I assume) happens here:
- calling this.setState({}); will change the App's internal state und thus trigger the rendering of a new frame.
- passing the animation call to window.requestAnimationFrame(this._animate); will result in an endless loop where the browser calls _animate() 60 times per second.
- the endless loop will be interrupted when the App (component) will be unmounted.
anyone with a deeper insight, please feel free to extend my very superficial explanation.
