BaselinePosition
is an option that specifies where the baseline of an object is considered to be for purposes of alignment with surrounding text or other expressions.
Details
- BaselinePosition is an option for such objects as Graphics, Grid, and TabView.
- BaselinePosition->pos specifies that position pos in an object should align with the baseline of surrounding text or other expressions.
- Possible settings for BaselinePosition are:
-
Automatic default object baseline Bottom bottom of object Top top of object Center halfway between top and bottom Axis axis of the object Baseline baseline of the first text line Scaled[y] fraction y of the height of the object i baseline of row i in a grid {i,j} baseline of element i,j in a grid {{i,j},pos} position pos in element i,j pos->ref baseline offset to make pos be aligned with ref - For objects that contain multiple lines of text, BaselinePosition->Baseline specifies that the baseline of the whole object should be taken to be the baseline of the first line of text.
- Scaled[0] corresponds to the bottom of the object; Scaled[1] to the top. If y is outside the range 0 to 1, Scaled[y] gives a baseline that lies outside the object.
- In BaselinePosition->(pos->ref ) the reference point ref can be Baseline, Axis, Bottom, Top, or Center. It can also be Scaled[y], where y represents a fraction of the total height of a single line of text in the current font.
- The reference point ref is relative to the line height of the default font surrounding the object. Top aligns with the top of the font's ascender, while Bottom aligns with the bottom of the font's descender.
- For objects that are typically a single line tall, such as Button and PopupMenu, BaselinePosition->Automatic generally corresponds to BaselinePosition->Baseline.
- For objects that typically span multiple lines such as Grid and Panel, BaselinePosition->Automatic generally corresponds to BaselinePosition->(Axis->Baseline).
- For text, the position of the axis is determined by the placement of - or a similar character. For other objects, the axis is taken to be the center, except when a construct such as a fraction bar or graphics axis defines another natural choice.
- Some settings of BaselinePosition are incompatible with the Full and Scaled settings of the vertical dimension of ImageSize. When these settings conflict, the BaselinePosition setting will supercede the ImageSize setting.
