Multi tab: hide/disable "drag and drop all tabs" SOLVED

[zarkogajic]

Hi devs,

Using muti tab viewer (Docs.SingleWnd = false).

How would I programmatically hide/disable "Drag and Drop all tabs" "tab" ?

Ok, solved with the help of this post: viewtopic.php?f=66&t=26530&

Ah ...

So, hiding the "drag and drop all tabs" by handling the "e_document_viewingStarted" and setting the UIX_LayoutItemStyle_NoTabBarGripperBtn - kind of works.

The e_document_viewingStarted seems to get fired only when a new document is loaded.

Now, having multiple tabs/documents open:

Sort the tabs:

and the TabBarGripperBtn gets visible again.

Question: what else to handle (and when) to set the UIX_LayoutItemStyle_NoTabBarGripperBtn ?

I want to remove that gripper button for good!

Hello zarkogajic,

The best way to ensure this would be to use the Custom Event Handler for the Document Views Area and listen to the:

Code: Select all

if (ni.nCode == (int)PDFXEdit.UIX_NotifyCodes.UIX_Notify_Layout_Changed)

From what I see, this will be fired all of the times that layout is being changed (even if you switch between the documents).

Cheers,
Alex

Hi Alex,

Thanks. This seems to do the trick.

Sadly, not 100%.

I can still reorder tabs by drag and drop - I'm ok with this and yes, I do not want to disable this by using UIX_LayoutStyle_PanesNoReorder.

But, I simply must disable drag-dropping a tab to move out of the main frame and open/goto/display another view (frame, window, however this is called) of the editor.

How to not allow the above?

Hello zarkogajic,

I've forwarded this to the appropriate developer, waiting for the reply.

Hi zarkogajic.

Sorry for delay with answer.

To hide the unnecessary buttons use it once:

Code: Select all

PDFXEdit.IUIX_LayoutItem tabsContainer = pdfCtl.Frame.View.DocViewsArea.Panes.Layout.Root[0];
int st = (int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_NoTabBarGripperBtn;
int stm = (int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_NoTabBarGripperBtn | (int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_ShowSortedTabsBtn;
tabsContainer.SetStyle(st, stm);

To prevent undocking the document tabs but keep ability to reorder them:

Code: Select all

public partial class MyEventCallback : PDFXEdit.IEventHandler
{
	public int documentView_ready = 0;

	public void Start(PDFXEdit.IPXV_Inst inst)
	{
		documentView_ready = inst.Str2ID("e.documentView.ready");
		inst.EventServer.RegisterNativeEventHandler(documentView_ready, this);
	}
	// PDFXEdit.IEventHandler
	public void OnEvent(int nEventID, PDFXEdit.IEvent pEvent, object pFrom)
	{
		if (nEventID == documentView_ready)
		{
			PDFXEdit.IPXV_DocumentView docView = (PDFXEdit.IPXV_DocumentView)pFrom;
			docView.Obj.Parent.LI.SetStyle((int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_NoFloat, (int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_NoFloat);
		}
	}
}

....

MyEventCallback eh = new MyEventCallback();
eh.Start(pdfCtl.Inst);

....

HTH.

Hi Vasyl,

Fantastic, thanks! Works like a charm.

Btw,

To hide the unnecessary buttons use it once:..

Cannot be called once, as when tabs are rearranged (sorted) the gripper button will re-display.

So, this must be called in the IUIX_ObjImpl implementation when pEvent.Code = e_Notify and ni.nCode = UIX_Notify_Layout_Changed, and then with this style:

Code: Select all

layout.Root[0].SetStyle(UIX_LayoutItemStyle_NoTabBarGripperBtn, UIX_LayoutItemStyle_NoTabBarGripperBtn OR UIX_LayoutItemStyle_ShowTabsThumbsBtn)

As I want to be able to activate the items using this button:

So, case closed

Yes, you are right - this wrong behavior caused by using the "Sort All Tabs Alphabetically" menu-item from the context menu.

We will fix that issue in the near future and instead of using it:

Code: Select all

PDFXEdit.IUIX_LayoutItem tabsContainer = pdfCtl.Frame.View.DocViewsArea.Panes.Layout.Root[0];
int st = (int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_NoTabBarGripperBtn;
int stm = (int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_NoTabBarGripperBtn | (int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_ShowSortedTabsBtn;
tabsContainer.SetStyle(st, stm);

you will be able to use once only the:

Code: Select all

int ncst = pdfCtl.Frame.View.DocViewsArea.Panes.Layout.NewContainerStyle;
ncst |= (int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_NoTabBarGripperBtn;
ncst &= ~(int)PDFXEdit.UIX_LayoutItemStyleFlags.UIX_LayoutItemStyle_ShowSortedTabsBtn;
pdfCtl.Frame.View.DocViewsArea.Panes.Layout.NewContainerStyle = ncst;

Cheers.
