vcl-styles

Using Delphi XE7 on a Windows 7 Pro 64-bit system. If I choose 'Charcoal Dark Slate' VCL style, the 16x16 pixel titel bar icon down-sized from the 32x32 program icon looks not like expected. It should look like the small icon below. If I load the program icon in 16x16 pixel format, it looks good in the titel bar, but ugly in the task bar because of the 16 to 32 pixel enlargement.

On a multi-monitor system, a "blank" VCL application maximizes fine, but the same application with styles enabled (and one chosen as default) maximizes incorrectly. What I'm seeing is the right-hand edge of the window extend onto the 2nd monitor (my main is on the left). When I started comparing to other Windows apps, I noticed that under Windows 7 (at least), maximized windows do not even have non-client borders on the left, right or bottom sides. And indeed, the standard VCL (non-styled) app behaves this same way, without non-client borders. How do I fix this? I notice that TFormStyleHook

I need to change the color of a TPanel when the VCL styles are enabled. I tried using and modifying the code listed in the article Changing the color of Edit Controls with VCL Styles Enabled , but it is not working for a TPanel. How I can change the color of a TPanel with the VCL Styles enabled? The TPanel doesn't use a style hook to draw the control, so you can't use the technique described in the article. instead you must override the paint method. Check this sample using a interposer class. type TPanel=Class(Vcl.ExtCtrls.TPanel) protected procedure Paint; override; End; Uses Vcl.Styles, Vcl

A TDateTime picker is a ComboBox where the drop-down list is replaced with a calendar. I use XE2 VCL Styles and changing style does'nt affect TDateTimePicker Color & Font Color. I have change the Calendar style with this question but the solution is not OK for the ComboBox , any idea ? Now I plan to inherit a TComboBox for use with a TMonthCalendar but I would know if anybody had a better solution. In order to use the workaround of the CalColors property, you must disable the Windows Theme in the drop down window of the TDateTimePicker component, for that you must use the DTM_GETMONTHCAL

I am using the new VCL styles system in Delphi XE2. It works great, but I wish to disable it for a particular form that has a number of images on it (a splash/about form). Problem is I can't seem to find a property of the form that associates it with a particular style, and so can't disable it for that form only. There only seems to be the global TStyleManager class which appears to be static. With this in mind, is the only way to achieve this to call TStyleManager.TrySetStyle('Windows') , show the form, and then set it back to the original style when the form is closed?

Is there a good VCL Styles tutorial where we see how to dynamically (in run time) load/change the style ? This should work with Delphi XE2 and up, since XE2 is the first version with VCL Styles. I'm adding an answer because local information is often preferred to just links. Here's the key facts you need to know before you start: Many VCL controls have color properties, but those properties are going to get ignored when styles are on, and the default "common controls" like Button are going to get drawn by Delphi itself, instead of using the XP or Windows 2000 style that "comes with windows".
