In the CHM export section of Project settings dialog you can configure visual appearance of exported CHM file. CHM export settings are mosly similar to those of HTML export settings.
To open the project settings, use one of the ways described below:
Here you can set the default topic that will be displayed when the user opens the CHM file. Click the arrow down button to select the topic from the project's topic tree.
Use this field to specify the subfolder for image files.
During CHM export a temporary folder will be created. HTML and image files will be placed into this folder. If you want the image files to be stored in an pictures subfolder, type "pictures" here. Otherwise, leave this field blank.
Check this option to keep temporary files in work folder after CHM compilation. Usually it's needed if you're planning to modify these files yourself after export and compile CHM file from modified files.
Press this button to specify your own CSS code to override CSS generated by Dr.Explain. This way can customize the appearance of CHM pages: fonts, colors, sizes, etc.
Use this section to configure the structure of the page: show or hide the menu, index and search tabs.
If you select checkbox Always keep header and footer viewable, the height of the generated pages will be automatically adjusted to fit to the height of the CHM viewer window. The header, footer and sidebars will be docked to the window's sides while the central content part will remain scrollable.
Select checkbox Pop-up tooltips over clickable areas to enable pop-up tooltips that will be displayed when the mouse pointer moves over the callout on the annotated screenshot. The tooltips will display the control description of the associated control, so that the user doesn't have to scroll the page down to read it.
