Hi, is there any way to listen to a TableColumn of a TableViewer to get informed if the size has changed?

have placed some textfields over the TableViewer and want to resize them when size of the tableviewer columns have changed.

Well what i actually need are the bounds of the table header fields, for each one. so when some of them resize, i want to resize the textfield

THx

Hi,

you can use TableColumn#addControlListener for listening of column
resize event.

Thx,

but is there any way to find to get the bounds of the TableColum? or at least the x coordinate of a column ? i want to place exactly over each column search text fields and they should reisze together with the corresponding column. only value that i can get from the TableColum is width, but i need the x position after the column is resized. Or do you know another way to realize that ?

Thx, Edin

Hi Edin,

you have to calculate the x position of the column yourself - see
TableColumn#getLeft.

Hi, Ivan

there is no getLeft method for the TableColumn class. Do you think about this one? http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse. platform.doc.isv/reference/api/org/eclipse/swt/widgets/Table Column.html
That is the class that im using. Do i have to cast it to some other class?

THx, Edin

i solved it, i hold the first item of the table, then i use the get bounds(int i) method on it to get the rectangle for the cell at that position and then i take my x, y, width, height whatever.

Thx, Edin

Hi Edin,

I'm speeking about RAP class TableColumn... and its private method
getLeft(). You can do it in a similar way in your code.
-----
final int getLeft() {
int result = 0;
TableColumn[] columns = parent.getColumns();
int[] columnOrder = parent.getColumnOrder();
int orderedIndex = -1;
for( int i = 0; orderedIndex == -1 && i < columnOrder.length; i++ ) {
if( columnOrder[ i ] == parent.indexOf( this ) ) {
orderedIndex = i;
}
}
for( int i = 0; i < orderedIndex; i++ ) {
result += columns[ columnOrder[ i ] ].getWidth();
}
return result;
}
------

Best,
Ivan

Hi Ivan

Could you elaborate more on getLeft() implementation. I don't see parent(Table).indexOf() method. I need to compute bounds for a clicked TableColumn() in a Table.

Thanks
Jatin Vasa

Hey guys, thnx for your help,

that is exactly what im looking for (overview and posibillity to see how the actual default theme is defined). Anyway, when i try to change Menu element, it has no effect for me. It stays gray. Im actually working with standalone version of RAP 1.5. so i have to create the shell on my own, and then add Menu instance. The MenuItems are correctly changed.
In my css im using this:
Menu {
color: #FFFFFF;
background-color: #0099CC;
}

And the menu is created on this way:
this.shell = new Shell(Display.getCurrent(), SWT.NO_TRIM);
Menu menuBar = new Menu(shell, SWT.BAR); //this remains gray, css has no affect!
MenuItem mainMenuHeader = new MenuItem(menuBar, SWT.CASCADE); //this works fine!

ANy idea why?

Is there a posibillity for a Widget to get its theme settings programatically and change them on the runtime. For example i have TableItem and if table is editable then css pointer property should be different then if its not editable. Or just simply to change the color and backgroundcolor (without setting it over SWT SYSTEM COLOR)?
