FriendFeedUse Images with Tab Labels

Step 1: Create a bitmap resource with the images
You can also use icons or even create the images at run time. In this example, however, lets stay with the bitmap since it is so much simpler. A single bitmap contains all the images and the images should be laid out horizontally as shown below. You can create the bitmap with an reasonable height and the image list will use it for the individual images. You can also select any reasonable width for the images as long as they are all the same. I say 'reasonable' because the size of the images should be in proportion to the height of the label. The bitmap shown below is 13 pixel high and each image is 13 pixel wide. The height and width need not be the same.
Step 2: Add member variable of type CimageList
Add a member variable to the CPropertySheet derived class. You will need to derive from the CPropertySheet class if you are not already doing so.protected: CImageList m_imageTab;
Step 3: Override OnInitDialog() and add code to it.
The code to add images to the tab labels should be placed in the OnInitDialog() function. After calling the base class version of OnInitDialog() we create the image list. The first argument to the create function is the resource ID of the bitmap we create in step one. The second argument is the width of each image in the bitmap. We had drawn the bitmap with each image 13 pixels wide. The third argument is the number of images that the image list should grow by when more images are added to it. Since we don't anticipate adding more images to the image list, this value is 1. The final argument is the color that will be treated as a transparent color. We have chosen white to be the transparent color since we used white as the background color when drawing the image.The next step is to associate the image list with the tab control. Finally, specify an image for each tab item.
BOOL CMyPropSheet::OnInitDialog()
{
BOOL bResult = CPropertySheet::OnInitDialog();
m_imageTab.Create( IDB_TABIMAGES, 13, 1, RGB(255,255,255) );
CTabCtrl *pTab = GetTabControl();
pTab->SetImageList( &m_imageTab );
TC_ITEM tcItem;
tcItem.mask = TCIF_IMAGE;
for( int i = 0; i < 3; i++ )
{
tcItem.iImage = i;
pTab->SetItem( i, &tcItem );
}
return bResult;
}

ReplySpace allocation problem

When you add images to tabs, tabs will require more space. It may happen that tabs will require more lines after adding images, but this additional space is not added automatically (property sheet does not resize). I think you can fix this by calling
SetActivePage(GetActivePage());
before you return from the OnInitDialog of your property sheet.

You need to add the line:
m_imageTab.Detach();
right before "return bResult;" at the end of the function. This will fix an assertion error you get the "second" time you open the property sheet.

My bitmaps are long (as the text was) for each tab button. But the button
Replydoesn't allocate enough space for the images. How can I set the length
of the buttons?
bitmaps in the tabs of property pages
Posted by Legacy on 09/30/1998 12:00amOriginally posted by: Peter
Hello,
I am working on an application containing some property pages embedded
in a property sheet. I tried to place bitmaps in the tabs of the
property pages as described in your article.
It is working fine the first time I open the dialog but the second time the bitmaps dissappear.
Do you know the solution to this problem?
I would be very glad if you can give me some hints.
In advance thank you very much for your help.
Best regards,
Peter
