|

|
|
* available width is used and how the available width is distributed between those frames
|
|
* The inner table frame has already a quite sophisticated treatment of percentage widths
|
|
* (see BasicTableLayoutStrategy.cpp). So it acts as master in the below computations.
|
|
* There are four possible scenarios
|
|
* a) None of the frames have a percentage width - then the aInnerWidth and aCaptionwidth will not change
|
|
* b) Only the inner frame has a percentage width - this is handled in BasicTableLayoutStrategy.cpp,
|
|
* both widths will not change
|
|
* c) Only the caption has a percentage width - then the overall width (ow) will be different depending on
|
|
* the caption side. For the left side
|
|
* ow = aCaptionMargin.left + aCaptionWidth + aCaptionMargin.right + aInnerwidth + aInnerMargin.right
|
|
* aCaptionWidth = capPercent * ow
|
|
* solving this equation for aCaptionWidth gives:
|
|
* aCaptionWidth = capPercent/(1-capPercent) *
|
|
* (aCaptionMargin.left + aCaptionMargin.right + aInnerwidth + aInnerMargin.right)
|
|
* this result will cause problems for capPercent >= 1, in these cases the algorithm will now bail out
|
|
* a similar expression can be found for the right case
|
|
* d) both frames have percent widths in this case the caption width will be the inner width multiplied
|
|
* by the weight capPercent/innerPercent
