I am using a CellTable on a ScrollPanel in GWT. My table has two columns and I want to give 10% and 90% of the width each. This is fine.
The problem is that I want to have one line of text per row in the table. That is if the content of one cell is too large to be showed in one line, I want to have either a horizontal scrolling bar or just truncate the text to fit it in one line.
Here is an extract of my code:
cellTable.addColumn(column1);
cellTable.addColumn(column2);
cellTable.setWidth("100%", true);
cellTable.setColumnWidth(column1, 10.0, Unit.PCT);
cellTable.setColumnWidth(column2, 90.0, Unit.PCT);
I also tried to use:
cellTable.setTableLayoutFixed(true);
but it doesn't change the layout.
Thanks a lot for your comments!
Use the CSS property "white-space: nowrap"

You'll have to play with the word-wrap, overflow and possibly text-overflow CSS properties.

So, I have a growing string with many "\n". Every app start I will load the total string and every app use some new lines will be added.
The string is inside the Content of a ScrollView. But the Content size is not scaling with the string length. I want the Content to be exactly as high as the text lines go and be scrollable.
I can think of calculating the line count and set the content height manually. But maybe there is a more simple way? Please tell me your solutions.
I found a convenient non-code answer myself. You put the Text-Component directly on your Content GameObject. Then you use a ContentSizeFitter and set Vertical: Preferred. Also the Content anchors have to be set for variable height.
This enables me to dynamically set and scroll through a different text length with a ScrollView. (The font size is kept, to still fit the rest of the GUI)
I am still open for other answers.
I'm trying to add spaces in between rows in an NSTableView, like how it looks here.
Currently, however, my rows look like this, with 0 spacing between them.
Is it possible to add these spaces? I found this post on how to do it, but that's for UITableView, and I don't think you can add sections with NSTableView. Another thing I tried was using intercellSpacing on the table view, like so:
tableView.intercellSpacing = NSSize(width: 0, height: 80)
However, that just increases the height of each row rather than increase the space between them.
Lastly, I looked into drawSeparator, which seems promising but has limited documentation. Would extending NSTableRowView and overriding the drawSeparator method work, basically by drawing in a blank space as the separator? If so, how would I go about making my table view use my custom row view class?
If none of these options work, I'd also be open to faking the effect, maybe by having the actual content of a row be smaller than the row itself and using the remaining space as the padding between rows. However, I'm not sure if this would work, given that right now I'm using NSShadow, which highlights the boundary of each row.
Found a way to work around this issue. Before, each row consisted of two columns, one for the text fields and one for the buttons. However, I've changed it by putting all the text fields and buttons into a single column, that way there's only one cell per row. I then can apply the NSShadow and other styles to the NSTableCellView rather than the NSTableRowView. This means that I can now use intercellSpacing to create vertical spacing between cells:
tableView.intercellSpacing = NSSize(width: 0, height: 80)
The rows are still touching, but I've disabled the borders/highlighting on them so you can't actually see them. The cells, on the other hand, are visible, and you can adjust the spacing/styles on them as necessary.
I think this is more of a general issue. I would like to use a textfield that gets dynamic data and doesn't stretch more than a given max height. For instance, I have a textfield that, if it gets text that fits in one line, the textfield will be one line height, and i have other elements under it, that will move up with float positioning. Or, if I want a 3 line max height and if the text exceeds that space, then the rest will be trimmed.
I don't want to use java expressions to trim that text, as it is not always accurate. I am new to jasper and I am trying to know if there is any way to do this. I did a lot of searches, but maybe there is something that i missed, and i hope someone can help me. Thank you
I managed to solve this by extending net.sf.jasperreports.engine.fill.TextMeasurer and overriding initialize() method; also I had to extend net.sf.jasperreports.engine.util.AbstractTextMeasurerFactory and override the createMeasurer() method.
Now, whenever I want to have max # of lines, with no overflow, I add a property to that text field (e.g. maxLines) which is being passed to my custom TextMeasurerFactory. I hope this helped you.
We had a similar problem at work with JASPER Reports 4.5, where we had an invoice with a header and a table. We wanted the header to have dynamic height based on the lengths of certain fields (like address, partner name, etc,), but not more than a critical limit, otherwise the header will push the table and thus making a mess by splitting it across multiple pages. Also, the invoice shouldn't exceed 1 page.
We eventually had to move the header in the background section, where we also put a background for the table consisting of vertical lines (so it will extend to the end of an A4 page) and a white opaque square.
This way, if the header exceeds the max height it will go underneath the table's background, cropping the text. This was the desired effect we were looking for.
Sounds crazy, but it worked ...
I am using a Gwt DataGrid with multiple Columns. The default behavior of the columns is to wordwrap. I would like for one of the columns to not wordwrap and just cut off. Is this possible?
For example, currently this is displayed:
I am making a
sandwich
I would like it to display:
I am making a
In addition to overflow:hidden you may need white-space:nowrap and finally add a text-overflow: ellipsis so there is an indicator to the user that the incomplete text is being shown.
You can set overflow: hidden in the style of each Column.
You can use DataGrid.addColumnStyleName to set styles on individual columns, or just addStyleName to add a style to the whole widget.
I have a problem with DataGrid in gwt 2.4. I made table with CellTable, and everything worked fine. But I needed fixed header, and then just replaced CellTable with DataGrid. I had problem with .css file, but than has been resolved.
Now, the problem is that every column have fixed width, and table put every row just in visible part of screen.
This is new and old screen shots, to make things more clear :)

Can someone help to make old looking, but with fixed header.
You can set a fixed width for each column of the data grid:
dataGrid.setColumnWidth(sampleColumn, 40, Unit.PX);
and expand the total data grid width:
dataGrid.setWidth("100%"); // choose the most useful in your app
dataGrid.setWidth("1400px");
I'm not sure what the right answer is, but I don't think the previous responders understood the question.
Basically, you want dataGrid to use "table-layout: auto" instead of "fixed". This is what cellTable does. Table columns are auto-sized based on content.
This is easy for the content table, but to get the header-freeze, dataGrid is using a separate div/table for the header. Therefore, the header table's columns need to be explicitly sized based on the data table. They also need to be resized anytime the table changes (browser resizes, etc.). I plan on adding resizeable cols on a dataGrid, so I'll be hitting this same challenge soon I expect and will update when I have something more explicit if anyone is still tracking this thread...
need to wrap your content in your td with an inner div. and make sure the overflow-x is set to hidden.
table {
overflow: hidden;
white-space: nowrap;
table-layout: fixed;
}
td div{
overflow-x:hidden;
}
