class TStyleManager: public TGMainFrame
TStyleManager This class provides a Graphical User Interface to manage styles in ROOT. It allows the user to edit styles, import / export them to macros, apply a style on the selected object or on all canvases, change gStyle. Activate the style manager by selecting Edit menu / Style... in the canvas window. The Style Manager interface is composed of two parts: - the top level interface that manages a list of styles; - the style editor, which deals with the current style settings./*

The combo box 'Available Styles' contains the list of available styles for the current ROOT session and shows the currently selected one. The field on the right shows the setting of the gStyle. You can set the global variable gStyle to the selected style by clicking on the button in the middle. The group frame 'Apply on' displays information for the currently selected canvas and object in the ROOT session. This selection might be changed by clicking on another object with the middle mouse button. You have a choice to apply a style on the selected object or on all available canvases. WARNING: You cannot undo the changes after applying the style! If you are not sure of that action, it may be better to see a preview of what you are going to apply. If the check button 'Preview' is selected, a preview of the selected canvas according to the selected style will be shown. The selection of the next check button 'Run Time Preview' will apply updates of the preview any time a value of the selected style is changed. For drawings that take a time it is better to disable this option. Create a new style: A new style can be created via the Style menu/New... or the toolbar. A clone of the selected style will be used as a base of the new style. All its values can be modified via the style editor later. The dialog that appears will ask for the name and description of the new style. Import a style (from a macro): A style macro can be imported at any time. The new imported style in the ROOT session will become the selected one. Import a style (from a canvas): You can do that selecting the Style menu/Import from.../Canvas or the corresponding Tool bar button. A new style will be created in the ROOT session and will become the selected one. This style is a clone of the gStyle with modified values as they are set in the currently selected canvas. You can import a style from any canvas and apply it later on some objects. Export a style (in a C++ macro file): To store a style longer than for the current ROOT session you can save it in a C++ macro file. This can be done via the menu or the tool bar button. There is a naming convention for the style macros: the name must be 'Style_*.C', where * can be replaced by anything you want. Delete a style: The selected style can be deleted from the list when you use the Style menu/Delete or the corresponding tool bar button. The selected style is removed from the list of all available styles for the current ROOT session. WARRNING: it will be lost if you didn't saved it in a C++ macro file before its deletion. Also, you cannot delete the selected style if it is set to gStyle. A message 'Can not delete gStyle' will be displayed on the CINT prompt./*

Editor's buttons: Open / close the style editor: The button 'Edit >>' opens the style editor and its label changes to 'Close <<'. For all details of what can be changed and how please see the provided Help. Reset a style (to a previously saved state): When the editor is opened, the 'Reset' button allows you to reset the values of the selected style for editing. Doing that you cancel all changes made since the last time you saved that style in a macro. If the selected style is one of the five ROOT styles (Plain, Bold, Video, Pub or Default), it will be recreated. Update the preview: The button 'Update Preview' is available when a preview is shown and the run time option is not selected. This button allows you to refresh the preview any time you want to see how the style you edit looks like. Help button: Provides a help of the currently selected tab.
