Mfc Propertygrid Control3/26/2021
If the width of the Propertygrid is smaller than this value, the horizontal scroll bar horizontally scrolls items in the Propertygrid.I used property sheet style tab pages with individual fields for each property and the number of control fields multiplied until the application teetered under the weight of all those windows.
Since then, I have become a big fan of Datagrid and Propertygrid style UIs. Ideally, at any one time you have one window displaying data and another to edit the data, yet maintain the illusion of a rich interface with many controls well organized. I wanted to have such an interface for my Win32 projects, something easy to use, ultra light weight, and professional looking. I noticed a promising property Listbox by Noel Ramathal as well as another by Runming Yan that appears to be based upon Noels work. I started from these examples but strove for something that had a similar look and feel to the Visual Studio Propertygrid as well as the one used in the Pelles C IDE. In addition to this, I wanted to write this Propertygrid as a message based custom Win3264 control. One way to handle this is to call the initializer in the WinMain() method of the application just after the call to InitCommonControlsEx(). It is called only once, the first time a new Propertygrid control is instantiated. An item must be part of a group or catalog as identified by the lpszCatalog parameter. Here is a snippet that demonstrates how properties are loaded into the grid. It is also necessary to declare and initialize a PROPGRIDFDITEM. The following figure identifies the various fields of the file dialog popup that are populated by these PROPGRIDFDITEM struct fields. It is also necessary to populate the lpszzCmbItems parameter. In the demo, I want to be able to add items to this list so I created the buffer via malloc(). The following figure shows the dropdown populated by the list. If dynamic updates are not necessary, then ignore the notifications and simply request the data when desired. Mfc Propertygrid Control Code For EachTo demonstrate the class in a useful context, I put together a demo that includes code for each supported item type. This field is only valid for items of type PITCOMBO and PITEDITCOMBO lpszPropDesc: The property (item) description iItemType: The property (item) type identifier. To make this easy and as a way of documenting the messages, I created macros for each message. If you prefer to call SendMessage() or PostMessage() explicitly, please refer to the macro defs in the header for usage. The height, in pixels, of the items, or LBERR if an error occurs. If the item is selected, the return value is greater than zero.
