Description

rImprovedComps unit contains set of enhanced components, usually introducing many new functions and fixing some bugs (eg. high DPI): TrGroupBox, TrImageEx, TrMemoEx, TrComboBoxEx, TrButton, TrStringsHolder, TrEditDate, TrEditNum, TrImageListEx, TrTabControlEx + TrPageControlEx.

TrListBox, TrColorBox, TrColorListBox, TrCheckListBox - fix for high DPI

TrGroupBox - provide new type of groupbox with following functions: - headline caption with definable colors and possition; - 4 types of frames with definable colors; - min max buttons with automatical and animated functions; - gradient background or background image; - support dropping of files to box; - support automatic resizing of children components

TrImageEx - enhanced TImage with following functions: - bound label with definable possition; - drawing support for basic shapes (rect, elipse, halfelipse)

TrMemoEx - enhanced Memo component which provides highlighting of words in text according list of words or highlighting of text between start and stop tag

TrComboBoxEx - enhanced ComboBox component which provides automatic setting of dropdown listbox width according length of items text, multicolumn dropdown, and internal timer for delayed event after editing

TrButton - enhaced TButton with following functions: - new property ImagesDisabled which is used for disable state of button instead of DisableImageIndex, so the same image list as for toolbar and menus can be used

TrStringsHolder - non visual component containing Strings object for editing in design time and storing in application

TrEditDate - enhanced TEdit component which provides functionality for editing of date value

TrEditNum - enhanced TEdit component which provides functionality for editing of integer or float number

TrImageListEx - enhanced ImageList component which provides storing of images in external compressed resource file in design and runtime and can block storing images in DFM file for descendant modules, so list can be used in ihnerited forms

TrTabControlEx + TrPageControlEx - enhanced TabControl and PageControl - provides colored tabs, hottrack fonts, color and border; - close button in tabs; - function for reading active tab caption and changing of active tab - supports Themes, use rStyleHooks unit to add Styles support for XE2 and higher

Updated version compatible with Delphi2010+ and 64bit platform. Splash screen in demo version.
