the button is automatically generated by the ActionCell in gwt, I want to change the width and height of the generated button, any method?
I chekced the ActionCell has no any addStyleName to allow me to change the css of the button.
You have several options.
If you use this cell in a CellTable or DataGrid, set the style on a column which is built using ActionCell:
myColumn.setCellStyleNames("myButtonStyle");
You can also set this style on the parent element which includes ActionCell:
.myButtonStyle button {
background: red;
}
or, even more specific, if necessary:
.myButtonStyle td button {
background: red;
}

While developing a card, I used a pseudo-class for a component to implement a color changing effect. However, the color cannot be restored.
For example, the original background color of a picture was yellow.See Image
This figure shows the new background color after using the pseudo-class. It is red now.
See Image
In normal cases, the card’s background color is changed upon tapping, and will return to the original color when you lift your finger. So how to achieve this?
Simply add a tap event to the component using the pseudo-class. No logic processing is needed.
Sample code:
<div class="sitetype_box" widgetid="8e4bf1ca-f716-46f8-8614-16d1b35002c5" onclick="test">
</div>
CSS style:
.sitetype_box {
flex-direction: column;
background-color:#FFBF00;
padding: dpConvert(0) dpConvert($elementsMarginHorizontalL) dpConvert(0) dpConvert($elementsMarginHorizontalL);
}
/** Pseudo-class */
.sitetype_box :active{
background-color: #E40078;
}
Method:
test(){
console.log("message");
}

In my part class I removed #Focus annotation method which implemented
#Focus
public void setFocus() {
viewer.getControl().setFocus();
}
after that tab text underline not visible. But when open window with single part tab text underline is visible, if I click anywhere on window underline gone.
How to remove tab text underline?
The underline is drawn if the CTabFolder used for the part has focus. So you should always define an #Focus method for the part and set the focus to some other control in the part.
The actual drawing of the tab is done by the tab renderer which you can set in the CSS using swt-tab-renderer:
CTabFolder
{
swt-tab-renderer: url('bundleclass://org.eclipse.e4.ui.workbench.renderers.swt/org.eclipse.e4.ui.workbench.renderers.swt.CTabRendering');
}
However tab renderers are rather complex and difficult to write.
The actual code in the standard renderer for the underline is:
if (parent.isFocusControl()) {
Display display = parent.getDisplay();
if (parent.simple || parent.single) {
gc.setBackground(display.getSystemColor(SWT.COLOR_BLACK));
gc.setForeground(display.getSystemColor(SWT.COLOR_WHITE));
gc.drawFocus(xDraw-1, textY-1, extent.x+2, extent.y+2);
} else {
gc.setForeground(display.getSystemColor(BUTTON_BORDER));
gc.drawLine(xDraw, textY+extent.y+1, xDraw+extent.x+1, textY+extent.y+1);
}
}
parent in this code is the CTabFolder (from org.eclipse.swt.custom.CTabFolderRenderer)
In gridColumns i am setting the rowDrag: true. This creates a default icon for all the rows having children or single rows. But i wanted to have this icon only for particular rows by setting the visibility of a drag icon as hidden.
More over if i populate rowDrag true or false conditionally, then rows for which i dont want drag icon, icon won't come but its breaking the alignment. That's why i want something explicitly where i can set the rowDrag for all rows as true and then explicitly set the visibility as hidden.
Please help me in this case. not finding any solution.
If you just want to hide the drag icon you need to override the CSS. Just assign css class to the rows you want to hide and then in the CSS file make the visibility as hidden.
Assign class as below
this.rowClassRules = {
"hide-row-drag-class": function(params) {
if (params.node.rowIndex % 2 == 0) {
return true;
}
}
};
Override CSS file
.yourTheme .yourClass .ag-row-drag{
visibility: hidden;
}
The above code assigns a CSS class to all odd rows and then will hide the row drag icon based on the CSS

In my page I have a Gxt ContentPanel with a white background. However, when the user mouses over the Header of the ContentPanel, I would like the background to change colors.
I tried achieving this by using the protected addStyleOnOver method of Gxt Component, but it doesn't have any effect. Is there anything else I need to do to use that methods (I'm already sinking the ONMOUSEOVER and ONMOUSEOUT events), or a better way to change the background?
you can do this using below code its working
ContentPanel contentPanel = new ContentPanel();
contentPanel.setStyleName("background");
and write below code in your css
.background:hover .x-panel-body {background-color: red !important;}
i'm not sure if this works, but you can test it...
final ContentPanel test = new ContentPanel();
test.getHeader().addListener(Events.OnMouseOver, new Listener<BaseEvent>() {
#Override
public void handleEvent(BaseEvent be) {
test.getHeader().setStyleName("your_new_style");
// or test.setStyleName("your_new_style");
}
});
You could simply add a style to the header, then add some css to change the color.
test.getHeader().addStyleName("my_style")
# css
my_style:hover { background-color: yellow; }
This is a bit trickier if you want to change the bg of the whole ContentPanel during onMouseOver of the header, in which case, add the mouse over event to the header where handle event adds style to the content panel (or content panel body depending on what you want), then add the appropriate styles to you css.
# css
my_style { background-color: yellow; }
I am using a TabLayoutPanel in GWT and I want to have the last tab show up on the right side of the page. Is it possible to do this?
Common idea:
set tab container width to "auto" instead of predefined "16384px"
set "float: right" css property to last tab
move last tab to firts position
public void onModuleLoad() {
.....
// init TabLayoutPanel
.....
Widget rightTab = tabPanel.getTabWidget(0).getParent();
DOM.setStyleAttribute(rightTab.getElement(), "float", "right");
Widget tabBar = rightTab.getParent();
tabBar.setWidth("auto");
tabPanel.selectTab(1);
}
If you want to align all tabs to right try this:
.gwt-TabBar .gwt-TabBarFirst {
width: 100%;
}
.gwt-TabBar .gwt-TabBarRest {
width: 4px;
}
.gwt-TabBar .gwt-TabBarFirst-wrapper {
width: 100%;
}
Short Answer - NO.
I drilled down to the source at GWT 2.3 and AFAIK it easier to build your own composite from TabBar and StackLayoutPanel than start fighting this implementation.
Just to save you an effort it cannot be centered easily too.
I am sorry it is like this.
it all hardcoded...
private static final int BIG_ENOUGH_TO_NOT_WRAP = 16384;
private final FlowPanel tabBar = new FlowPanel();
...
tabBar.getElement().getStyle().setWidth(BIG_ENOUGH_TO_NOT_WRAP, Unit.PX);
Why not pure CSS solution ? It is good practice to separate your code from design.
.gwt-TabLayoutPanelTabs {
width: auto!important;
}
.gwt-TabLayoutPanelTab {
float: right;
}
Remember that your tabs will come in reverse order (first added will be first on the right)
It is possible and will be very easy if you create your own tab.Just create an png image of tab shape (which is having rounded corner at top).Write one css rule.Take one FlextTable and apply that css to each cell that will be your tabs and then add that FlexTable into another mainTable. So in your mainTable in first row there will be tabFlexTable and in second row whatever you want to display after selecting particular tab.So for the first row apply horizontal alignment to right. This the way and same way I am also using in my professional projects.
