Multiple Toolbars in the PocketPC 2002

Download demo project - 29.7 Kb

Sample Image - CeMultiBar.jpg

Introduction

This article presents a solution on how to implement multiple toolbars in a PocketPC 2002 application. The idea came from an exchange in the Embedded/Mobile message board where this functionality was sought, especially the Pocket Word-like management of the toolbar ( http://www.codeproject.com/script/comments/forums.asp?forumid=13695#xx435722xx).

Implementation

The demonstration project (illustrated above) has two toolbars that are hidden or shown through commands in the main command bar. Note: the demo project is meant to illustrate the working of the toolbars, so no functionality has been implemented on them.

Both toolbars are created in CMainFrame::OnCreate without the WS_VISIBLE style. When the user issues a command to show a toolbar, the window is shown and RecalcLayout is used to reposition everything inside the frame.

void CMainFrame::OnToolbarFormat() 
{
    CToolBarCtrl& rToolBar = m_wndCommandBar.GetToolBarCtrl();

    m_bFormat = !m_bFormat;

    m_wndFormat.ShowWindow(m_bFormat ? SW_SHOW : SW_HIDE);
    RecalcLayout();

    rToolBar.CheckButton(ID_TOOLBAR2, m_bFormat);
}

Note that there are no ON_UPDATE_COMMAND_UI handlers in the demo. Checking and unchecking of the main command bar buttons is done explicitly in this message handler.

A final note on CToolBar: I found no proper way to have it draw the top border, so I derived the dummy class CCeToolBar with the single purpose of drawing the top border. If there is a better way to achieve this, please post it here.

Não acredito que a abordagem com o eVB seja a mesma (na verdade não conheço o eVB assim tão bem para me poder pronunciar). Esta solução depende muito da estrutura de janelas imposta pelo MFC, que não deve ter paralelo no eVB. Regards, João Paulo Figueira Embedded MVP

Question!

This idea is very great! But I can't add this style bar to my sample. My sample is based on MFC(CMainFrame & CDocuments & CView). I added the codes to my CMainFrame class. As I click the trigger button on the original toolbar, the second bar would not show at all. I guess the View overlaid the second bar,that's right? Could you give me some advice? Thanks so much!

Simple, concise, very clear ! I was searching through MSDN documentation to have a toolbar above the command bar but it's not very clear there! Then I found your article ! Thank you !

This solution actually solve most of my problem, but i still got one problem. I modify this solution to create multi bar on dialog based application for pockect PC 2002. When i compile it, it always give me the error like this :

'RecalcLayout' : undeclared identifier

I am wonder is it this 'RecalcLayout' function only can't be use on dialog based application? If can't, how can i solve this problem?

it is urgent, i hope can get the answer soon.
Thanks.

`RecalcLayout` is a method of `CFrameWnd`, not `CDialog`. This method is used to automatically calculate the bars positions and then resize the client window accordingly. For a dialog, I'm afraid you will have to provide this functionality yourself. Toolbars can be created on a dialog as child windows, but you have to calculate their positions as `CDialog` will not help.

What about vertical toolbars?

aseiden

20:22 27 May '03

First of all, thanks very much! I've been trying to figure out how to do this.

Now, call me crazy, but here's what I'd really like: two toolbars, with the first one running along the bottom of the window just like normal, and another one running vertically along the right side of screen (that is, where the scroll bar would normally be).

Anyone have suggestions on the best way to do this?

Thanks very much!

Thanks for the great article , but how can I disable the red "tab-and-hold" circle of the toolbar buttons and show some tooltips like the `CCeCommandBar` does? Daniel --------------------------- Never change a running system!

Use this on CCeCommandBar:

void CCeToolBar::OnLButtonDown(UINT nFlags, CPoint point) 
{
	Default();
}

Daniel S. wrote:

In the protected part of CMainFrame's declaration, add the following code:

	LPTSTR	m_pszTipOffice[3],
			m_pszTipFormat[4];

Now, go to the CMainFrame::OnCreate method and, just before the return statement, add this code:

	m_pszTipOffice[0] = _T("Paint");
	m_pszTipOffice[1] = _T("Check");
	m_pszTipOffice[2] = _T("Italic");
 
	m_pszTipFormat[0] = _T("Left");
	m_pszTipFormat[1] = _T("Center");
	m_pszTipFormat[2] = _T("Right");
	m_pszTipFormat[3] = _T("Justify");
 
	m_wndOffice.SendMessage(TB_SETTOOLTIPS, 3, (LPARAM)m_pszTipOffice);
	m_wndFormat.SendMessage(TB_SETTOOLTIPS, 4, (LPARAM)m_pszTipFormat);

Have fun!

Just out of curiosity, how do you test your programs during development? Like, do you have your Pocket PC constantly connected, or do you have a regular PC with Windows CE 2002 on it? Regards, Vitaly Tomilov Professional tooltips for all development platforms Free on www.Tooltips.NET

I first started working with the emulator, but it is not very stable. Tipically it would randomly send a perfectly updated W2K Pro to the boot sequence (not even a blue screen). So I had to buy an iPAQ 3950 (a year ago, now) and it is always on. Regards, João Paulo
