Description

A way to ensure your elements appear just like you want them to.

Automatically constrains forms at runtime, at the size used in designtime. A way to ensure your elements appear just like you want them to. You could say this one enables constraints at default, but WITH the ability to change it in designtime any way you like. Normally, setting constraints to any maxwidth etc, will not allow you to change your mind after that, unless you change the maxwidth etc again. This one lets you change it to any size you want in designtime, while keeping the constraints enabled. It is set to Active:= True by default, which, enables the component but can be set to Active:= False which disables it.

Description

• Enables application to use dynamic registration of classes
• Enables application to interact with list of dynamically registered classes
• Takes off responsibility from programmer to add RegisterClass on BPLs
• Allows for applications to use real plug and play BPLs as runtime modules extensor
• Expanded module extensibility using BPLs allows your application to generate and mantain a list BPL held classes without having to explicitly register them with the RegisterClass procedure
• GetDynRegClasses procedure allow you to explore list of dynamically registered classes
• DynUnRegisterClass and DynUnRegisterClasses allows you to unregister classes on one by one or module wise basis
• Work In Progress - based on Ludovic Dubois' "Classes hack" found on borland.public.delphi.opentoolsapi newsgroup) which is the only code I found to delegate RegisterClass responsibility

The Delphi TButton control does not permit multiline captions or captions with mixed colors, fonts or styles. However, this is easily done since buttons do have the intrinsic ability to host other controls such as labels. The steps to be followed are discussed here. A fully functional demo, with source code, of an extended button is included.

"There are a few "TDBTreeViews" on the internet now. Most of them are shareware and - this is the reason why I wrote this - didn't work like I had expected. Some are very powerful but need a complex data structure to work. Of course, a real DBTreeView is more comfortable. This Example shows you how to make a simple TreeView behave like a DBTreeView."

There are many more things possible with Delphi than one can make up from the poor help files that accompany it. There is virtually no conceptual help available from the standard help file, and that is just what can be so helpful for programming. I always try to not use any 3rd party component, so I can publish my stuff where and how I like it. Do not use 3rd party components if you do not have to, apart from the fact that doing it yourself gives much more satisfaction.

This very short tutorial shows you how to add a progress bar to any web browser programs you make in less than 2 minutes. It is very basic, and kept as short as possible, you can figure out most of the code just by looking at it. Aimed at beginners, this gives you an easy and quick way to have a working progress bar which informs the user of the progress the web browser is making. You can then focus on the other tasks like for instance the graphical representation to make it the way you want it. Included is the completed example. I hope this little bit of conceptual knowledge will help you. I like to hear your opinion, comments, problems you may have while using this helpfile, this goes for all of my published stuff, please email me.

TMyOpenDialog demonstrates a possibility of enhancing the common Windows open dialog by means of a dialog template. TMyOpenDialog is not a recreation of Windows open dialog from scratch, but its true ancestor.

This example shows how to:

• add control s to the open dialog, change their properties and "see" their events;
• use standard Help button and fire an OnHelp event after it's clicking;
• use standard "?" button and a right-mouse context menu to show a Help hint for controls in a dialog (including added ones).

The TreeMenu is a descendant of TTreeView.

It is a "stealth-realese" because the TreeMenu is created only run time and it changes a design time defined simple TreeView to self.

Description

This is an implementation to a TTreeView’s node so it would automatically expand or contract when an object hovers over it, during a Drag/Drop operation.

Unfortunately, if no special code is added, the treeview gets messy and a full repaint is need.

To fix this behaviour, TTreeview is subclassed in order to access the dragObject and use the HideDragImage/ShowDragImage methods.
