Detailed Description

Custom Table View Class.

Implementing our own table view class derived from the Wt one. This implementation is designed to be layout aware.

Member Function Documentation

handleMouseDown()

void GCW::Gui::TableView::handleMouseDown ( const Wt::WModelIndex &  _index, const Wt::WMouseEvent &  _event  ) -> void

protected

Handle Click Event.

This handler responds to 'click' events in the view.

The intent here is to provide some 'handling' when the user is mouse-ing around the table view. He should be able to click around to get editors to open, and select rows and whatnot.

The 'purpose' for the handler is due to the fact that the view responds differently if the view is editable or not. For instance, if an index is read-only, clicking on it causes the view to 'select' the entire row. But, if the index is 'Editable' then you are placed in to the editor but the view 'selection' is still visible, even if it's on another row. Further, the editor widget that opened, did not signal to the rest of the row that it should be 'selected'.

layoutSizeChanged()

auto GCW::Gui::TableView::layoutSizeChanged ( int  width, int  height  ) -> void

override

Upon a table resize, size the columns appropriately.

Parameters

int	width Full table width
int	height Full table height

Definition at line 258 of file TableView.cpp.

setColumnWidth()

auto GCW::Gui::TableView::setColumnWidth ( int  column, const Wt::WLength &  width  ) -> void

override

Overload setColumnWidth so we can save what the user specifies into our map. This implementation can take both absolute and relative (percentage) widths. Percentages are interpretted as the percentage of non-allocated width remaining. i.e. if a table is 100px, and one column has an absolute width of 20px, then the two following relative columns should both use 50%, which would yeild 40px each (minus padding.)

setVisibleRows()

auto GCW::Gui::TableView::setVisibleRows ( int  rows ) -> void

inline

Set the number of visible rows before a scroll bar appears
