SCI_SETTABMINIMUMWIDTH(int pixels)
+ SCI_GETTABMINIMUMWIDTH → int
+ SCI_SETTABMINIMUMWIDTH sets the minimum size of a tab in pixels to ensure that the tab + can be seen. The default value is 2. This is particularly useful with proportional fonts with fractional widths where + the character before the tab may end a fraction of a pixel before a tab stop, causing the tab to only be a fraction of + a pixel wide without this setting. + Where displaying a miniaturized version of the document, setting this to 0 may make the miniaturized + version lay out more like the normal size version.
