Is there a component I can download or buy that looks and behaves like the Delphi IDE tool palette?
What I need is a component similar to this to display different items under different categories.
The items I want to populate it with are not components like TEdit, TButton etc but just regular list items which could be anything, and could have any custom icon.
Could anyone suggest or recommend me to any available components like this?
I am using Delphi XE.
What do you know I have discovered the component TCategoryButtons actually inside Delphi.
This seems to be the same type of component.

Win7 must give ok style for TSpinEdit, but I see outdated style:
So arrows are not themed, and buttons are old.
I use Delphi7. How to patch VCL to fix style?
OK is:
I don't know if Delphi 7 already had it but you can use TEdit in combination with TUpDown and then set the Association property of the TUpDown to your TEdit.
TSpinEdit is a custom VCL control. There is no Windows control with that functionality. Even in the latest version of Delphi it looks exactly the same as in Delphi 7. And it's really rather ugly isn't it?
The control, in modern Delphi, is implemented in a unit named Vcl.Samples.Spin. Looking at the documentation for the Vcl.Samples namespace we have:
Contains the units for several sample VCL components delivered with RAD Studio - a calendar, an outline, a gauge, and a spinbutton.
The unit will be named differently in Delphi 7, but the principle is the same. These are sample controls, supplied with source code.
So, what you may do is take a copy of the TSpinEdit code, and modify the painting. Change the button drawing to be how you wish it to be.
I have hundreds of components in my Delphi 2006 installation, but I always have trouble finding those I haven't used before and that may be the solution for what I need at the moment. I have many undocumented packages, but by the name of the component you can have an idea of what it does.
For example:
I need a RadioButton, so I have TRadioButton, TElRadioButton or TAdvRadioButton to choose which one has the custom properties that I need.
But when I click the Filter Button of the Tool Palette, I have to Type from the beginning of the component name. If I could have a field editor where I could type only a part of the name and the Palette showed me the components that had that term in the middle of the name too, I would make my day!!!
Does anyone know how in Delphi 2006?
I know that Delphi XE2 has this filter field.
The DDevExtensions IDE extension (http://andy.jgknet.de/blog/ide-tools/ddevextensions/) has a Component Selector that does what you need
(also using D2006, so it definitely works)
I'm using RAD 2010 on windows 7 and all visual components looks normal (Edit, DBCombobox, for example) but the dblookupcombobox has the same border theme from Windows XP. I can't find how make it's looks like the other components. Anyone has any idea of how i can make this?
Thanks PS: Sorry by the bad english.
I have discovered that the reason for this behavior it that TDBLookupComboBox is a descendant of TCustomControl. Most similar controls are descendants of TCustomEdit, TCustomComboBox or TCustomListBox, which all call TWinControl.CreateSubClass to utilize a preregistered System Window Class of EDIT, COMBOBOX, and LISTBOX, respectively.
Since neither TDBLookupComboBox nor any of its ancestors do this, it just gets a plain border drawn due to the WS_BORDER flag in its Params.Style.
I'm going to assume there is a valid reason that TDBLookupComboBox does not call CreateSubClass to get a Windows COMBOBOX, but I'm not sure why. Maybe a future version of the VCL will utilize this.
I have lots of components installed - trouble is when I want to find one I rarely use it takes ages to find it. I can look at the ALL choice which lists all components but finding one with say 'grid' in the title is still very time consuming. Is there a database of titles or (preferably) a text file I could interrogate and search?
Try DDevExtensions 1.61, it add ability to search for components for Delphi from version 5 and above, with other many improvement for the IDE.
Which version of Delphi? In recent versions, just click on the top of the palette and type "grid". Ctrl-Alt-P will focus the palette, and then you can just start typing.
In RAD2009 and RS2010, do this and it'll find all components with "grid" anywhere in the title.
Since you didn't specify which version of Delphi...
1) In older versions (D7 and before), you can right click on the component palette to see the properties. This shows all of the components you have installed one page at a time. It isn't searchable, but at least the list shows each component's name and package, so it's easier than using the popup hints on each individual component.
2) In Delphi 7, you can select View|Component List, which brings up a searchable alphabetical list of all components. Unfortunately, it only matches on the first part of the component name. The first version of the "new" tool palette had this same limitation.
3) DDevExtensions (free) allows partial string matches in the old component palette (D5-D7), and restores something like the old palette in newer versions of Delphi (D2005 and up). It's also included in Delphi 2010 for people who prefer that style. I like how the search works in Delphi 7, but in Delphi 2010, the filtering seems a little awkward to me. It filters the components and palette pages, but if you have matching components on more than one page, they aren't all shown at the same time. You still have to click on each individual page.
4) My favourite. I prefer the new tool palette (Delphi 2005 and up). Very configurable, lets me see the component names, shows components on more than one page at a time, dockable, etc.
Bottom line. If you don't have or don't like the new tool palette, get DDevExtensions.
Before Delphi 2005: Install DDevExtensions, then choose Tools -> DDevExtensions Options -> Component Selector -> Check the "Active" box, click OK
Delphi 2005 and later: Click in the component palette and type the name of the one you want.
Use GExperts - they help a lot.
I need to switch every control of a particular type on a form to a different type while maintaining the name and the code associated with each control.
For example, let's say I need to switch a dozen or more TEdit fields to TSpinEdits. How can I do that in Delphi 2007 with minimal effort?
Use the GExperts Replace Components expert. It's free, and is the only tool I've seen that does what you're asking, including mapping properties from the old component to the new one.
If you don't feel like using any external tools, you could always try switching to view the form as text, then search and replace TEdit to TSpinEdit. When you switch back and save the form, the IDE should tell you that the declarations in the .pas file are incorrect and offer to correct them automatically. Property mappings shouldn't be a problem unless there are properties that are named differently that you want to map from one class to the other. Properties that don't exist on the new class will be deleted. This is how it works in Delphi 7 anyway...
If you're not happy with the results, you might try GExperts as recommended by Craig, which are a great addition to the IDE for many reasons.
I use the CNTools component replacer (couldn't find the one in GExperts), it's got a good Component Selector feature too so you can select multiple controls based one some simple queries.
