I need ag-grid to be responsive on all devices. When I tried this.gridApi.sizeColumnsToFit() It looks nice on desktop, but in mobile screen column width gets zero
as shown in this image.
When I give this.gridColumnApi.autoSizeColumns(allColumnIds, false); it leaves a blank space if there are less number of columns like shown in this image.
Is there a way to autoFit in desktop and autoSize in smaller screens?
you can call them after another. I'd suggest to first call the autoSizeColumns.
Afterwards you calculate the actual tableWidth with something like
const tableWidth = grid.columnApi.getAllColumns()
.reduce((i, current) => i += current.getActualWidth(), 0);
and then you calculate the actual container width
const {left, right} = grid.api.getHorizontalPixelRange();
const containerWidth = right - left;
and only if the tableWidth is smaller than the container width you call `sizeColumnsToFit``
if (tableWidth < containerWidth) {
grid.api.sizeColumnsToFit();
}

In ag-Grid, if the columns occupy a smaller space than the width of the grid, a blank hole appears on the right of the last column. Please see below (example taken from ag-Grid docs):
The UX designers on my team don't like that. They would like to see the rows extended all the way to the right to balance out the look. Is this possible to do with ag-Grid?
Edit: We don't want to use the sizeColumnsToFit option, because on large monitors it produces very wide columns and the grid becomes unreadable. We want to use the autoSize option to compact the columns and fill the hole on the RHS with blank stripes as suggested above.
Yes it is possible. You can call the sizeColumnsToFit function on the ag-Grid api which will fill out the width of the table with the columns.
Take a look at documentation.
Here is a plunker example.
EDIT
Use the property suppressSizeToFit and set it to true to when you call sizeColumnsToFit, it won't have an affect. Apply this property to the defaultColDef and set it to false for the last column. This was, when you call sizeColumnsToFit, only the last column will be set to full width. See the updated plunker above.
this is how i do it:
/**
* if there is "dead space" present on the grid, the columns will be auto sized to fill the gap
* #param gridApi
* #param columnApi
*/
resizeColumnsToFit(gridApi: GridApi, columnApi: ColumnApi, allowShrink = false) {
if (allowShrink) {
gridApi.sizeColumnsToFit();
} else {
const gridBodyWidth = document.getElementsByClassName("ag-root-wrapper")[0].clientWidth; // todo: use grid's id instead of [0] to allow multiple grids on a page
const allColumnsWidth = columnApi.getAllDisplayedColumns().map(c => c.getActualWidth()).reduce((a, b) => a + b, 0);
if (gridBodyWidth > allColumnsWidth) {
gridApi.sizeColumnsToFit();
}
}
}
This method will size columns to fit only when there is "dead" space on the right. Optionaly set allowShrink to true to force resizing even if there is no dead space
I had the same situation and resolved with the following css override:
.ag-center-cols-container {
width: 100% !important;
}
One possible option I've been playing with is adding a fake column at the end to fill the remaining space. To do so, you just need to add a column with options similar to the following to the end of your list of columns:
{
flex: 1,
headerName: '',
}
See this plunker forked from #ViqMontana's example above.
It's not a perfect solution, but wanted to mention it here in case it helps.
This works like Craig Weston's answer but without the need for !important:
.ag-center-cols-container {
min-width: 100%;
}
All my searches turned up for sizeColumnsToFit and autoSizeColumns which is not what I want.
My grids have many columns, so it scroll horizontal which is fine
But I cannot know in advance what would be the most space needed for the widest text in a column, so want the grid to auto size all columns to accommodate for whatever is the longest line of text in the cell.
Can one do that? (pretty much like have nowrap on a html table column, not that ag-grid wrap text, it just hide what is too long)
Grid Resizing:
https://www.ag-grid.com/javascript-grid-resizing/
sizeColumnsToFit - this tries to squeeze all the columns in the view - no horizontal scrolling
autoSizeAllColumns - this tries to size all columns to to fit the data - horizontal scrolling
// If you need to resize specific columns
var allColIds = params.columnApi.getAllColumns()
.map(column => column.colId);
params.columnApi.autoSizeColumns(allColIds);
// If you want to resize all columns
params.columnApi.autoSizeAllColumns();
I passed through this and it took me some time to make it work the way I wanted to, by that I mean :
Use all the available space
Make each column take the width required to display its content correctly
Solution :
Add the width parameter for each column (requires some manual tuning to set the right values)
Call gridApi.sizeColumnsToFit() in the onGridReady which will resize to take the available space while making sure that columns having bigger width will take more space
const gridOptions = {
...
columnDefs: [
{
...,
width: 100
},
{
...,
width: 50
},
...
],
...
onGridReady: (event) => event.api.sizeColumnsToFit();
};
Simply use flex instead of width in the column definitions. The grid will adjust automatically.
You can find a complete example for auto resizing all column.
column-sizing
Simply call autoSizeColumns() function, all columns will be resized according to content.
gridColumnApi.autoSizeColumns(allColumnIds, skipHeader);
If I create a Label in a 500x500 area with wordwrap, how can I find out the height of the wrapped text ? I'm looking for the yellow height, not the salmon height.
Answer of #idrise doesn't work for system font And here I give a more flexible answer.
Assume we want to create a text/label which has a fixed width, but dynamic height according to text's length. for that you can use below code:
Label *lbl = Label::createWithSystemFont("aaa aaa aaa aaa aaa aaa", "Arial", 50);
lbl->setDimensions(FIXED_WIDTH, 0); // "0" means we don't care about wrapping vertically, hence `getContentSize().height` give a dynamic height according to text's length
////
auto dynamicHeight = title->getContentSize().height; // According to text's length :)
And obviously for fixed height you can do similarly.
Hope Help someone :]
This may seem a little counter intuitive.
First you set the dimensions with an excessively large height.
Calling getLineHeight and getStringNumLines will calculate the height based on the width passed.
You send the width and height back to setDimensions.
Now your labels getContentSize() will return the actual size of the text.
IE
label->setDimensions(width, 2000);
label->setDimensions(width,label->getStringNumLines() *
ceil(label->getLineHeight()));
They added the functionality you want:
Added three overflow type to new label: CLAMP, SHRINK, RESIZE_HEIGHT.
Overflow type is used to control label overflow result, In SHRINK mode, the font size will change dynamically to adapt the content size. In CLAMP mode, when label content goes out of the bounding box, it will be clipped, In RESIZE_HEIGHT mode, you can only change the width of label and the height is changed automatically. For example:
//Change the label's Overflow type
label->setOverflow(Label::Overflow::RESIZE_HEIGHT);
mTexto=Label::createWithTTF(mTextoHelp.c_str(),CCGetFont(), 30);
mTexto->setHeight(100.f);
mTexto->setOverflow(Label::Overflow::RESIZE_HEIGHT);
mTexto->setDimensions(mSize.width*0.8f, 0.f);
I created a game object which acts as a repeating item for a UIGrid which I populate dynamically. The gameobject (RowItem) has couple of UILabel whose text can change on runtime depending on the content. The content of these UILabels overlap when the text is bigger. Can anybody help me in how to make UILabel expand relative to the adjacent UILabel when the text is more/less?
You can use transform.localScale property of the UILabel's property to scale it. Just make them bigger when the text is bigger than let's say 20 characters. Try with arbitrary values.
Also when you change the scale, run a re-align method, which aligns other labels so that they don't overlap.
you can get the text length in pixel by this:
UILabel label;
float width = label.relativeSize.x * label.transform.localScale.x;
float height = label.relativeSize.y * label.transform.localScale.y;
Let's say that you want to set you max length to 100, you can do this:
if (width > 100)
{
label.localScale = new Vector3(100 / label.relativeSize.x, 100/ label.relativeSize.x, 1);
}
the second param for Vector3 is also based on relativeSize.x is not a typo, that makes sure your text will not become thin.
Hope this works.
Are it's possible to resize vb6 inner form, because if i use Form1.Height or Form1.Width it's including window border height and width, so i just can use this code in one window theme (ex. it's work best in WinXP with XP theme, but not work in WinXP with Classic theme, it's seen too long), any suggestion?
What you can do is compare the Width (the outside size) to the ScaleWidth (which is the inside size) to get the size on the non-client border. Likewise, you can compare the Height to the ScaleHeight to get the non-client size at the top and bottom. From that you can set your final height and width based on the inner (client area) size you want plus the non-client size.
Something like this could go in your Form_Load:
Const DesiredClientHeight as Single = 3435
Const DesiredClientWidth as Single = 3345
Dim fNonClientHoriz As Single, fNonClientVert As Single
fNonClientHoriz = Me.Width - Me.ScaleWidth
fNonClientVert = Me.Height- Me.ScaleHeight
Me.Width = DesiredClientWidth + fNonClientHoriz
Me.Height = DesiredClientHeight + fNonClientVert
Be aware that the form width and height are always in Twips, so if you change your scale mode to something other than twips you will need to account for that.
