Hi everyone.
I have a problem when I showing Yes/No Dialog to user when is loading Perspective. I need show menu Item by perspectiveId. If i dont open messageBox, menu is correctly displayed, but when is showed, somehow perspectiveId is not set to open perspective but stay id parents perspective (perspective from witch is called a handler to open this one). At first i thing its delay or new window problem, but I try show message with Swing and Its fine. Problem is probably in SWT widget logic.
I give you some notes to better understanding.
I'm asking to user if they want to use dynamic grid (its own component to display data in grid from database) in moment when creating configuration of data source for grid, its same moment when showing gridView witch is part of showing perspective.
Hire is part of code where I asking
@Override
protected IGridContentSource<Subject> getGridContentSource() {
final IAdressService adressService = CtxHolder.getService( IAdressService.class );
max = adressService.getCountSubjekt( null );
if ( max > step ) {
final Shell shell = new Shell(PlatformUI.getWorkbench().getDisplay(), SWT.ON_TOP);
MessageBox messageBox = new MessageBox( shell, SWT.ICON_QUESTION | SWT.YES | SWT.NO );
messageBox.setMessage( "Record is " + max + ", use dynamic grid?" );
messageBox.setText( "Warning" );
int response = messageBox.open();
if ( response == SWT.YES )
useDynamicGrid = true;
}
code of my perspective
public class AdressPerspective implements IPerspectiveFactory {
public static final String RCP_ID = "xxx.rcp.app.AdressPerspective";
@Override
public void createInitialLayout( IPageLayout layout ) {
String editorArea = layout.getEditorArea();
layout.setEditorAreaVisible( false );
layout.addStandaloneView( ViewNavigacionTreeAdress.RCP_ID, false, IPageLayout.LEFT, 0.25f, editorArea );
layout.getViewLayout( ViewNavigacionTreeAdress.RCP_ID ).setCloseable( false );
layout.addStandaloneView( SubjectGridView.RCP_ID, false, IPageLayout.TOP, 0.5f, editorArea );
layout.addStandaloneViewPlaceholder( AdressGridView.RCP_ID, IPageLayout.TOP, 0.5f, editorArea, false );
...
Hire is part of my plugin.xml

If I active other perspective and go back, menu is correctly displayed. So i tried print id of active perspective (immediately after loading) in global handler activated by keys, and its print correct id. So i think problem is when is processing menu. Maybe in plugin.xml. But still I cant understand why it is happening when I show SWT messageBox, maybe its problem of shell when i showing message in new windows in moment when I want redraw other one. maybe some mishmash in focus
PLS someone HELP, if you have experience with it, or just have a tip. I'll be a glad
I'm sorry of my English, but is not my mother Language; sorry of part of code, I'd like give more, but i developing commercial product.
Now i probably have less time (Christmas & Holidays), so be patient and all of you Merry Christmas and New Year
