I am using ipywidgets to create a Dashboard with voila
I have a Textarea as follows:
comm_text = widgets.Textarea(value='',
placeholder='OK',
description='',
style=style,
layout=widgets.Layout(height="auto", width="auto"))
what I pretend with height="auto" is that when entering lines in textarea the text box expands vertically accordingly. (I want to have all the text visible)
It actually does not happend.
As you can see in the screenshot I introduced 8 lines but the textarea does not expand along.
Is that at all possible?
If not, what does actually height="auto" stand for?
If you change
layout=widgets.Layout(height="auto", width="auto")
for
layout=widgets.Layout(height="100%", width="auto")
It will resize to display all the text that it had on the value (default value for the Textarea).
However it won't grow as you type. I don't remember any textarea that does that on webpages.
One more thing. If you are using grids, with height="auto" and you resize the Textarea (dragging by the corner), it will resize other related elements of the grid.
That won't happen if you use height="100%"
The parameter height='auto' sets the CSS of the widget to 'auto'. But it has no effect for a textarea, because the number of rows are hard-coded. Jason Grout speaks of this in this Github post.
If you want a growing text area, you could use this workaround:
def get_bigger(args):
comm_text.rows = comm_text.value.count('\n') + 1
comm_text = Textarea(value='',
placeholder='OK',
description='',
rows=1,
layout=Layout(width="auto"))
comm_text.observe(get_bigger, 'value')
comm_text
Disclaimer: I don't know if this behavior is useful. You will give up control how big the textarea can get.

Is it possible to set a x-scrolling in react-virtualized? I have a table with a fixed width, and more columns to display than I got space in my table, so I need a x-scrollinig. In my tests if i did it, the table just shrinked up and did just display '...''s for content if the table runs out of space.
Intro paragraph for react-virtualized Table docs (emphasis added):
Table component with fixed headers and windowed rows for improved
performance with large data sets. This component expects explicit
width and height parameters. Table content can scroll vertically but
it is not meant to scroll horizontally.
You might be able to hack it, but it isn't meant to support horizontal scrolling so it probably won't work. Consider using Grid or MultiGrid instead if this is a requirement for your app.
I was struggling with this myself for a while. I did it by by setting the width of the table to width={Object.keys(rows[0]).length*150} and set each column min width to 150 (or whatever you choose just make sure it is the same in your table).
Then wrap it in a Paper and give it a width and overflowX:'auto'
something like this:
const VirtualizedTable = withStyles(styles)(MuiVirtualizedTable);
export default function DataPreview(props) {
const rows = [{ One: 'one', Two: 'Two',Three: 'Three',Four:'Four', Five:'Five', Six:'Six'}]
return (
<Paper style={{ height: 400, width:700, overflowX: 'auto'}}>
<VirtualizedTable
width={Object.keys(rows[0]).length*150}
rowCount={rows.length}
rowGetter={({ index }) => rows[index]}
columns={Object.keys(rows[0]).map(head=>{return(
{
minWidth:150,
label:head,
dataKey:head
}
)})}
/>
</Paper>
);
}
Building on bvaughn's accepted answer, the hack for a horizontally scrollable table could look something like this, however, beware of the following caveats that come with this hack:
Your overflowing Table columns will not be virtualized
The scrolling focus gets captured by the wrapper's x-axis scrolling and you will need to click within the internal Table component to refocus and regain y-axis scrolling. This is incredibly frustrating to use especially on mobile devices.
I am using JDeveloper 11.1.2.3.0,
I have an inputFile component in my page that takes its text value from the name of some components. The problem is that that when the text is long it gets displayed all there and may even occupy the whole window. Is there any possibility to wrap this text value in this case?
I don't think <af:inputFile> has a labelStyle attribute:
You can try adding the CSS in the component's inlineStyle or contentStyle
<af:inputFile inlineStyle="word-wrap:break-word;" />
It depends if the very long text is in the content or the label of the field.
If this doesn't do the trick, you can try creating a custom skin and customizing the label or content style via the adf style selectors: af|inputFile::content , af|inputFile::label.
Btw, you need to check if word-wrap works on all browsers you're targeting.
You can try setting the labelStyle attribute of the <af:inputFile> component to wrap the contents of the label. I am not sure of the CSS style attribtue information for it, but searching on the net I found word-wrap:break-word;.
I too had this problem with af:inputFile.
Just give contentStyle="width:200px" it will solve the issue.
we can adjust the width accordingly.
So I load some simple HTML into a webview.
The html is in the format: (it is extracted html, therefore no body tags.
<p>..blah</p>
<div style="text-align:center;">
<a href="http://services.runescape.com/m=rswikiimages/en/2012/5/combat1-18140712.jpg" target="_blank">
<img src="http://services.runescape.com/m=rswikiimages/en/2012/5/combat1_thumb-18140804.jpg"></a></div>
<p>..blah</p>
In the webview activity class I add:
webInfo = "<body style=\"color:white;font-size:15px\">" + webInfo + "</body>";
//for setting the size and color of the text
I use the following to load the html:
webview.loadDataWithBaseURL(null,webInfo,"text/html","UTF-8",null);
// webInfo is an html string
and I do the following so that it doesn't scroll horizontally and so that the image fits within the screen.
webview.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);|
If I don't use SINGLE_COLUMN, I'm always scrolling horizontally, even though the text fits nicely within the page. I thought it had finally solved the problem but I get overlapping html when i load it. This fixes itself if I zoom slightly in or out with my fingers.
Here's a picture of whats happening:
Question 1:
How do I fix that problem and display the image so it fits in the screen and no horizontal scrolling is required?
Question 2:
I've also been having trouble getting rid of the weird symbols too, my 's show up really weird.Tried using several different encodings like UTF-8, US-ACSII and lots of Windows ones, none of them seem to work to get rid of the symbols.
I hope I've been clear, any help is appreciated, I've been fiddling with this for a while O_O...
Add in webview settings:
webSettings.setLayoutAlgorithm(LayoutAlgorithm.TEXT_AUTOSIZING) //handle for font overlapping.
I have a gwt button that has a fixed size.
I want to present a text on it, and if that text exceeds the button length, I need to cut it short and put "..." in the end. I use the following code now:
if(name.length() > 11){
//limiting the size of the text presented on the button
name = name.substring(0,10)+"...";
}
I have a list of such buttons, and this approach causes that not all button's text have the same size.
The problem is, for example, that 10 chars of "!" are much shorter than 10 chars of "A".
Can anyone help me with a way to solve this issue?
Thanks!
Fast answer. Try ussing HTML5/CSS3 property. It does exactly that:
http://www.w3schools.com/cssref/css3_pr_text-overflow.asp
If you need to do that for non-CSS3 browsers you'll need to make some kind of fake. Maybe setting a button div content, with overflow-hidden, and placing a floating "..." to the right. But it's more difficult...
You could add a style-class to all those buttons and fix their size.
Should be something like this:
First, add the style-class to each button:
Button button = new Button();
button.addStyleName("buttonSizeStandard");
Then add a matching style in the css file:
.buttonSizeStandard{
width: 200px; //change 200 to whatever
}
I need to display some Rich-Text in LWUIT.
I was thinking of HTML Component, but I can't get linewrapping there - probably an error on my side.
Another idea would be to use TextAreas or Labels and do it manually.
I'd need the possibility to have bold words in a non bold sentence.
Hello, this is a bold. <- This dot shouldn't be bold.
Is there a way I can achieve that? I think I only can use one Font per Component...
Use a Container with flow layout and just place labels into it. This is what the HTML Component does internally.
Try com.sun.lwuit.html.HTMLComponent class. Use it like,
HTMLComponent htmlComp = new HTMLComponent(null);
htmlComp.setBodyText("<b>Hello</b>, this is a <b>bold</b>. <- This dot shouldn't be <b>bold</b>.");
form.addComponent(htmlComp);
This component will allow you to use html tags inside text. For more information, refer this link: HTMLComponent
