Detailed Description

Window that puts a message and buttons like OK or Cancel.

The strategy is to create a new MessageBox, then immediately add buttons (with AddButton()) or other windows to it (through the base class RowFrame::AddWin()), before calling app->addwindow().

Todo:
standard buttons like OK or Cancel! or whole style like
Overwrite? Yes No Cancel
Save "blah"? Yes No Cancel
Save "blah" before quitting? Yes No
"blah" unsaved, quit anyway? Yes No
Todo:
*** incorporate automatic Control Tab Loop thingy ***first button is always ok?? *** must have a constructor specifically for blocking popups that auto-wrap to message extent, and send a message back
#include <messagebox.h>

Constructor & Destructor Documentation

Laxkit::MessageBox::MessageBox ( anXWindow parnt,
const char nname,
const char ntitle,
unsigned long  nstyle,
int  xx,
int  yy,
int  ww,
int  hh,
int  brder,
anXWindow prev,
unsigned long  nowner,
const char nsend,
const char mes 
)

Default is to add a new MessageBar if mes!=NULL.

The nstyle should be the same things you would pass to RowFrame. Currently what actually does get passed to RowFrame is nstyle|ROWFRAME_CENTER|ROWFRAME_ROWS.

Todo:
prev is ignored

Member Function Documentation

Button * Laxkit::MessageBox::AddButton ( const char btext,
int  sendid,
anXWindow prev = NULL 
)
virtual

Add a text button with btext as the label.

Clicking on buttons installed with this will cause the messagebox to be destroyed and message sent to the owner.

prev is passed to the Button constructor for the previous contron of a tab loop. Returns a pointer to the new Button. This can be used to close a tab loop, for instance.

References Laxkit::RowFrame::AddWin(), and Laxkit::SquishyBox::pad.

Referenced by Laxkit::InputDialog::InputDialog(), Laxkit::Overwrite::Overwrite(), and Laxkit::SimplePrint::SimplePrint().

Button * Laxkit::MessageBox::AddButton ( unsigned int  buttontype,
anXWindow prev = NULL 
)
virtual

Adds a button with a standard Button style define in buttontype.

Clicking on buttons installed with this will cause the messagebox to be destroyed and message sent to the owner.

prev is passed to the Button constructor for the previous contron of a tab loop. Returns a pointer to the new Button. This can be used to close a tab loop, for instance.

References Laxkit::RowFrame::AddWin(), and Laxkit::SquishyBox::pad.

int Laxkit::MessageBox::Event ( const EventData e,
const char mes 
)
virtual

Destroy on any ClientMessage.

If the message is a 'mbox-mes', then relay that message to the owner.

The data from the relayed event is not changed, but the message_type becomes this->sendthis.

Reimplemented from Laxkit::anXWindow.

Reimplemented in Laxkit::SimplePrint, Laxkit::InputDialog, and Laxkit::Overwrite.

References Laxkit::anXApp::destroywindow(), Laxkit::anXApp::SendMessage(), Laxkit::anXWindow::win_owner, Laxkit::anXWindow::win_sendthis, and Laxkit::anXWindow::WindowTitle().

int Laxkit::MessageBox::preinit ( )
virtual

This sets w and h to BOX_SHOULD_WRAP, which is supposed to trigger a wrap to extent. Then arrangeBoxes(1) is called. If the window sizes are then larger than the screen, the window is shrunk to be within the screen.

Todo:
***check this!!

If a window has a stretch of 9000, say, then that window is stretched to that amount, which is silly, so right now, the only way to prevent that is to subclass MessageBox and intercept preinit()....

Todo:
this needs a little more thought....

Reimplemented from Laxkit::anXWindow.
