I'm using a layout panel with some layers. One of the layers is quite simple but I want it to have a float: right on the element. But this is actually not working because subwidgets are styled with style="postition: absolute; left: 0px; ..." which overrides the styling and so the subpanels/widgets will always be placed on the left. Any workaround for this?
After adding your element to your layout container, did you try setWidgetHorizontalPosition ?
If above method does not work and you want to use float right, maybe you can use a non-layout system with FlowPanel maybe. Otherwise you will have to fix the position and width/height of your components but you may loose responsive design.
Last trick : If you really need to change the absolute style. In your component do something like this (do this after your component has been added to the dom)
this.getElement().getParent().getStyle().set.....
You can reset whatever property you want but this might break your layout

I want to zoom a GtkTreeView. Initially I thought I simply could use transform to do that, but it seems like GTK CSS currently does not support transform.
So reading up on the CSS docs, it seems my only chance would be to set font-size.
Now naively I tried to set font-size to 200% in GtkStyleContext.
All I get then is
g_object_set_is_valid_property: object class 'GtkStyleContext' has no property named 'font-size'
So how is one supposed to set font-size in code?
You can start with this:
css_provider = Gtk.CssProvider()
css = b"""treeview.view {font-size: 200%;}"""
css_provider.load_from_data(css)
style_context.add_provider_for_screen(screen, css_provider, Gtk.STYLE_PROVIDER_PRIORITY_APPLICATION)
But, this will set 200% to all treeviews.
If you want (and you probably do) a custom style class which you can attach to any widget, it should look something like
.my_style_class { font-size: 200%; }
And you add this class to specific widget's StyleContext:
widget.get_style_context().add_class("my_style_class")
Recently started working on a master detail structure angular ag-grid. The structure has two levels of master-detail nesting. I need to fix the heights of inner - 2 grids such that they occupy all available real estate on the screen. Currently, ag-grid defaults it to 300 px and a lot of whitespace or unused space appears on a 1920x1200 screen resolution monitor. I also need to have fixed headers for all grids.
Any ideas or pointers would be appreciated...
Update: Referring to a forked version of plunker example from ag-grid here - https://next.plnkr.co/edit/yUzo4EqONEmgCmIw This is simple and basic set up for master-detail grid.
Note that: I haven't set any detail row height and have setup just one record to show up in the grid to test for the issue.
If you run the plunker code and view the result in separate window, notice that the inner / child grid doesn't occupy all the space available below it. In other words, it doesn't take as much as space/height available from parent container (master's detail row). The default 300px master detailRowHeight is making height fixed for inner grid. Also, from documentation, detailRowHeight prop doesn't seem to take something similar as 100% or 100vh and only takes fixed pixels number. Added a picture of the example below and the height / unused space I referred
We have different resolutions that users use to view data in grid and the heights of inner grids need to auto-adjust taking max. available space to show most information in the grids.
You could try something like this, I pulled it from the documentation:
In your component.ts file add this method. If it's a detail row it will apply different calculations than the other rows.
public rowHeight(params) {
if (params.node && params.node.detail) {
var offset = 80;
var allDetailRowHeight = params.data.callRecords.length * 28;
return allDetailRowHeight + offset;
} else {
// otherwise return fixed master row height
return 25;
}
};
In your template add the following: [getRowHeight]="rowHeight"
<ag-grid-angular
#agGrid
style="width: 100%; height: 100%;"
id="myGrid"
class="ag-theme-balham"
[columnDefs]="columnDefs"
[masterDetail]="true"
[detailCellRendererParams]="detailCellRendererParams"
[getRowHeight]="rowHeight"
[rowData]="rowData"
(gridReady)="onGridReady($event)"
></ag-grid-angular>
Hopefully this will get you moving forward. Good Luck!

So I don't have a great, full solution for you but as a starting point I would use CSS to override the styles ag-grid is setting - I don't think detailRowHeight is going to help.
Here's my plunk getting close to what you want with some simple CSS I put in index.html. You can use !important to override ag-grid styles, or you could use javascript to set the CSS after ag-grid does. I prefer !important in this case and don't have to worry about timing.

The problem I wasn't going to get into is getting it to dynamically fill up available space, depending on the row selected, scroll position, etc. I can't think of any simple way to achieve that - I do this type of thing in grid often and end up writing javascript to calculate the available space, and then set the CSS in javascript.
In ag-grid you have the possibility to set auto height for details.
Set grid property detailRowAutoHeight=true to have the detail grid to dynamically change it's height to fit it's rows.
const gridOptions = {
// dynamically set row height for all detail grids
detailRowAutoHeight: true,
// other grid options ...
}
However if you are providing your own detail component...
detailCellRenderer: 'MyOwnDetailsComponent',
then, it might not work and you will still need to provide an grid options height detail content through...
detailRowHeight: 560,
Please see the ag-grid documentation here
I need to swap panels in a list. I've tried to reorder rows in a grid but I need to put a little more informations in the item so a panel will be nicely to show.
Must be the classic drag icon (four arrows) like here http://examples1.ext.net/#/DragDrop/Panel/Swap_Dropable_Panel/
This example is very close that I want. I need only vertical swap like this one http://tof2k.com/ext/sortable/ ( this could be just what I need but seems it don't use ExtJS themes and I don't know if I can put more information inside the items - and it is a little ugly too).
Some ideas?
Perhaps using a grid with a templatecolumn and drag and drop resolve your issue.
FIDDLE: https://fiddle.sencha.com/#fiddle/1i7l
Also, you can use CSS to change row.
.customRow .x-grid-cell-inner {
margin: 5px 5px 5px 5px;
background-color: yellow;
}
Remove de comment
//cls: 'customRow'
on fiddle (line 58).
I Would like to move the sorting arrow from left to right side in the cell table header which is shown in below image
Any Suggestion?
It took me a while to find, but the solution is very easy. Cell table uses default header builder which has an option to render sort icon on left or right side.
DefaultHeaderOrFooterBuilder<Contact> headerBuilder = new DefaultHeaderOrFooterBuilder<>(table, false);
headerBuilder.setSortIconStartOfLine(false);
table.setHeaderBuilder(headerBuilder);
Cheers!
I think I have some raw ideas you could play with and see if they help:
Get a handle on the div containing the arrow img, to add a style classname that will be used in a CSS selector [2. below] that styles the right-alignment you want... Maybe something like this would work:
CellTable.getTableHeadElement().addClassName( "myTableHeadersClassname" );
If 1. succeeded in getting "myTableHeadersClassname" classname on the CellTable's thead element, then I think we are in good shape. I think this CSS selector will then work:
.myTableHeadersClassName div div:nth-child(1){
left: auto;
right: 0 px;
}
I'm not sure if 1. will work, so that might be the hard part. But the idea is to add a classname somewhere in the CellTable DOM hierarchy to then create the CSS selector out of. As long as you can apply that classname and make the selector, you should be just faced with fiddling with that selector's style (although I think the style inside the selector in 2. should work at that point). If 1. doesn't work, I think you could always just put a classname on the top-level CellTable itself, and then have this slightly more complex selector:
.myCellTableClassname thead div div:nth-child(1)
Whichever selector route you go, the left style should be overriding CellTable's inlined style; if what I wrote does not do that, then just add more specificity to the selector until it does.
Hope some of this helps...
In menubar, normally submenu gets displayed on the right hand side. I want to change to Left hand side. Can anyone please let me know, how can I do it ?
Popup location of Sub menu is defined by CSS elements at rendering based on position of menu items.
Looking Via Firebug On Main Menu It produced:
element.style {
clip: rect(auto, auto, auto, auto);
left: 337px; // Change this to left:35px;
overflow: visible;
position: absolute;
top: 319px;
visibility: visible;
}
// This is main CSS for popup
.gwt-MenuBarPopup{
}
So, Give it a try by using setStyleName("css goes here") from code
I again advise you to override the default styles GWT:) I used this method on my project when I had to change some standard view of GWT-elements.
I was able to implement a solution by changing the css as well. Perhaps this isn't the most elegant way, but it works. Using a little help from GwtQuery's closest() method, here is a short example.
menuBar.addAttachHandler(new AttachEvent.Handler() {
#Override
public void onAttachOrDetach(AttachEvent event) {
if(event.isAttached()){
Scheduler.get().scheduleDeferred(new ScheduledCommand() {
#Override
public void execute() {
Element e = $(menuBar).closest(".gwt-MenuBarPopup").get(0);
e.getStyle().setLeft(parentMenuBar.getAbsoluteLeft()-menuBar.getOffsetWidth() , Unit.PX);
}
});
}
}
});
So the idea being when the child sub menu is attached, you want to change the css. I use a deferred command so that it will change the css after GWT's default MenuBar implementation sets it.
This line, "$(menuBar).closest(".gwt-MenuBarPopup").get(0);" will search up the DOM tree until it finds the element with the class .gwt-MenuBarPopup, which is the one you want to change.
My solution is somewhat of a hybrid of those posted so far here, but I think it is cleaner/simpler than any of them.
Each vertical subMenu is itself a MenuBar, added as an item to the top-level
MenuBar. For whichever subMenu you want to drop to the left instead of the right, add a style class name to it using .addStyleName("myLeftDropDownStyleName") on that MenuBar Widget.
Define the selector rule for that style like this (these are the minimum attributes that were necessary for me to get the left dropping):
.myLeftDropDownStyleName{
position: absolute;
right: 0px;
}
Absolute positions relative to the first parent element with a position other than static; for my case at least, that parent position seemed to be horizontal place where the dropdown otherwise has its left edge without this solution. I wouldn't be suprised if Relative position might work better in some other people's cases.
The Right offset of 0px tells the absolute position's right to be at that horizontal place I mentioned above. And of course the pixel size can be > 0 to push further to the left by that much, or even < 0 to pull it back to the right by that much.
This works perfectly for me, is simple & clean, and does not force all of your MenuBars to have this style (as I think would be the case if you overrode one of the GWT MenuBar styles themself).
