經(jīng)常性的,自己設(shè)計(jì)的對(duì)話框無(wú)法改變大小,沒(méi)有最大化最小化按鈕,等等.在哪里設(shè)置這些屬性呢?

JFace的Dialog繼承于Window類,該類中有一方法,設(shè)置Shell的樣式.

setShellStyle

protected void setShellStyle(int?newShellStyle)

Sets the shell style bits. This method has no effect after the shell is created.

The shell style bits are used by the framework method createShell when creating this window's shell.

Parameters:

newShellStyle - the new shell style bits

在Dialog的構(gòu)造函數(shù)中調(diào)用該方法,即可更改Dialog的樣式.下為一例:

import ?org.eclipse.jface.dialogs.Dialog;
import ?org.eclipse.swt.SWT;
import ?org.eclipse.swt.browser.Browser;
import ?org.eclipse.swt.layout.GridData;
import ?org.eclipse.swt.widgets.Composite;
import ?org.eclipse.swt.widgets.Control;
import ?org.eclipse.swt.widgets.Shell;

public ? class ?BrowserDialog? extends ?Dialog? {

???? private ?String?url;

???? public ?BrowserDialog(Shell?parent,?String?url)? {
???????? super (parent);
????????setShellStyle(getShellStyle()? | ?SWT.RESIZE? | ?SWT.MAX);
???????? this .url? = ?url;
????}

???? protected ?Control?createContents(Composite?parent)? {
????????Browser?browser? = ? new ?Browser(parent,?SWT.NONE);
????????browser.setUrl(url);
????????GridData?gd? = ? new ?GridData(GridData.FILL_BOTH);
????????gd.minimumWidth? = ? 600 ;
????????gd.minimumHeight? = ? 400 ;
????????browser.setLayoutData(gd);
???????? return ?browser;
????}
}

import ?org.eclipse.swt.SWT;
import ?org.eclipse.swt.widgets.Display;
import ?org.eclipse.swt.widgets.Shell;

public ? class ?TestDialog? {

???? public ? static ? void ?main(String[]?args)? {

???????? final ?Shell?shell? = ? new ?Shell(SWT.DIALOG_TRIM? | ?SWT.RESIZE? | ?SWT.MIN? | ?SWT.MAX);
???????? final ?Display?display? = ?shell.getDisplay();

????????String?path? = ? " C:/Temp/log.html " ;
????????BrowserDialog?dlg? = ? new ?BrowserDialog(shell,?path);
????????dlg.open();

???????? while ?( ! shell.isDisposed())? {
???????????? if ?( ! display.readAndDispatch())? {
????????????????display.sleep();
????????????}
????????}

????}
}
