@brief The QetGraphicsHeaderItem class
|
|
The header have a few parameters to edit her visual aspect.
|
|
Margins, to edit the margin between the cell and the text.
|
|
Text font.
|
|
Text alignment in the cell
|
|
These three parameters are not settable directly with the header but through the model to be displayed by the header.
|
|
Header search these parameters only in the section 0 for cell of header.
|
|
By consequence, set data in other section is useless also these parameter can't be set individually for each cell.
|
|
The margins is stored in the model in index Qt::UserRole+1 and for value a QString. See QETUtils::marginsFromString and QETUtils::marginsToString
